Summary of the Third Annual AEOIP Workshop

Introduction

The Applied Earth Observations Innovation Partnership (AEOIP) was established in 2018 to facilitate knowledge coproduction and optimization of NASA Earth observations that can be used by natural resource managers for decision making. Through continued iteration and reflection, coproduction brings together stakeholders to share responsibilities and the completion of activities towards a common goal. AEOIP enables strong collaborations between NASA and the U.S. Forest Service (USFS), along with growing participation from U.S. Geological Survey (USGS), Bureau of Land Management (BLM), and other federal land management agencies.

AEOIP has held several previous meetings: the first was a Joint Applications Workshop on Satellite Data for Natural Resource Management held April 29–May 2, 2019, reported in an Earth Observer article, “Summary of the USFS–NASA Joint Applications Workshop on Satellite Data for Natural Resource Management.” The group met again virtually in 2020 during PitchFest. In 2022, a virtual workshop on Integrating Remote Sensing Data for Land Management Decision-Making took place March 23–24, 2022. In 2023, the AEOIP workshop took place April 25–27, 2023, with a hybrid format – the in-person participants met at the USFS Geospatial Technology and Applications Center (GTAC) in Salt Lake City, UT. The 2023 workshop focused on Addressing Land & Water Monitoring Needs Using Remote Sensing Data.

These workshops have been designed to build connections between participants across the research-to-applications spectrum with subject matter experts from a variety of federal agencies and other affiliations to continue to promote interagency collaboration within the Earth Observations (EO) applications field. This goal is accomplished using interactive panels and guided discussion sessions that highlight new tools and techniques, promote NASA EO data product uptake, and foster connections between data providers and data users.

2024 Workshop Overview

The most recent AEOIP workshop took place April 23–25, 2024, with a hybrid format. The in-person participants met in Ann Arbor, MI. The three-day event had a similar structure to its predecessors but with a wildland fire management theme. Altogether, 135 people participated in the workshop, with 77 attending in person and 58 virtually – see Photo 1.

Meeting Objectives

The workshop objectives were to:

  • meet AEOIP’s mission by providing a forum for building new relationships among Earth observations data providers, users, and stakeholders;
  • gather and/or codevelop “shovel-ready” ideas to better leverage Earth observations to meet science and management priorities of U.S. land and natural resource management agencies;
  • gather needs for and/or develop educational materials to support the use of existing EO training resources for fire management; and
  • gather ideas for the 2025 workshop and other AEOIP activities.

Breakout Sessions

A large segment of this workshop was dedicated to four concurrent topical breakout sessions – referred to in this report as Breakout Sessions A–D. The topics covered in each breakout session are listed below, along with the name(s) of those who facilitated discussion.

  • Breakout Session A: Fuels, Wildland Fire Emissions, Carbon & Climate Andy Hudak [USFS] and Edil Sepulveda Carlo [NASA’s Goddard Space Flight Center (GSFC)/Science Systems and Applications Inc. (SSAI)];
  • Breakout Session B: Prescribed Fire Planning & Management Nancy French [Michigan Tech Research Institute (MTRI)], Birgit Peterson [USGS], and Jessica Meisel [University of Idaho];
  • Breakout Session C: Fractional Vegetation Cover Products & Decision Making – Tim Assal and Jake Slyder [both U.S. Department of Interior, BLM], and Liz Hoy and Amanda Armstrong [both at GSFC]; and Alexis O’Callahan [University of Arkansas].
  • Breakout Session D: Post-fire Effects & Recovery: Assess, Predict, Remediate, and Monitor – Mary Ellen Miller [MTRI].

All of the breakout groups met on each day of the meeting. On the morning of the first day, the facilitators of each group gave brief “elevator pitches” about each breakout topic, and participants selected a topic for focus. After that, a block of time each day was dedicated to breakout activities and discussions. Participants were asked to focus on different aspects of the topic each day. In the afternoon of the first day, each group focused on identifying needs and challenges in the area being discussed – with a brief report-out at the end of the day. On the afternoon of the second day, the focus was on data availability and solutions – i.e., finding ways to overcome obstacles to making data more readily available to users – again with a brief report- out at the end of the day. On the morning of the third day, there were topical presentations. Each group worked to synthesize their three days of discussions and chose a representative to give a summary report during the closing plenary later that morning.

Workshop Summary

The remainder of this article presents highlights from each day of the workshop. This includes the most important presentations given during the meeting and those given during the breakout sessions. The report also includes highlights from training breakouts given on the second day of the workshop and a summary of a prescribed fire field trip, which took place the day before the workshop and visited two locations – see Optional “Field Trip” for AEOIP Workshop Participants to learn more.

Optional “Field Trip” for AEOIP Workshop Participants

On April 22, 2024, an optional field trip was offered that featured two sites demonstrating prescribed fire in Michigan. For the first stop on the trip, Kevin Butler [Washtenaw County—Natural Areas Preservation Program Stewardship Supervisor] gave a tour of a prescribed fire site in Park Lyndon, a county park in the northwest part of Washtenaw County, MI. The park is being restored to maintain native species using prescribed fire as invasive species control. The intent of these efforts is to restore oak meadows and preserve over 500 species of plants across fens, marshes, ponds, forest, and prairie lands.

On the second leg of the trip, Tina Stephens [City of Ann Arbor—Volunteer and Outreach Coordinator] led a tour of Furstenberg Nature Area, in the city of Ann Arbor, MI. She highlighted the importance of prescribed burning to achieve ecological benefits. The 0.15-km2 (38-acre) park contains wetlands, woodlands, prairie, and oak savanna. Since the mid-1990’s, Natural Area Preservation staff and volunteers have maintained those ecosystems through controlled burns and invasive shrub removal. The second tour stop included a small prescribed fire demonstration – see Photo 2.

DAY ONE

On the first day, Kira Sullivan-Wiley [Pew Institute] gave a plenary presentation, in which she discussed the value of coproduction, which in the context of AEOIP can be described as honoring the generative capacity of others as a means of optimizing the use of Earth by natural resource managers for decision making – see Photo 3. The benefits of this approach include cost reduction, tracking new ideas, and empowering marginalized voices.

The first block of breakout sessions also occurred during the afternoon of the first day, along with a short report-out. In light of the keynote discussion on coproduction, deliverables from this meeting’s breakout sessions can be seen as coproduced, new or improved conduits between NASA and land-managing entities.

After the keynote, representatives of government agencies (NASA, USFS, and BLM) presented their respective agency’s perspectives. The manager of a nearby state park in Michigan followed with a local perspective. A series of short presentations in the late afternoon featured various program highlights from NASA’s Earth Science Division, which are not detailed in this report – see workshop agenda for list of programs and speakers.

Notable Presentations

In addition to Kira Sullivan–Wiley’s keynote (described above), Christina Moats-Xavier [NASA Headquarters, Earth Action Program—Program Manager for Mission Engagement] shared NASA’s perspective, focusing on NASA’s Earth Science-to-Action strategy, which aims to increase the impact of scientific data. NASA’s Applied Science Program is now included under the broader umbrella of the new Earth Action program element of NASA’s Earth Science Division. This strategy has three pillars: 1) scaling existing efforts; 2) building bridges; and 3) focusing on the user. By collaborating with NASA, AEOIP can address real-world challenges to develop solutions that benefit society. Overall, the presentations on the first day highlighted the importance of collaborative, user-centered approaches and community engagement in addressing environmental challenges.

Everett Hinkley and Frenchy Morisette [both USFS] provided a practitioner’s perspective. They discussed USFS efforts to address climate adaptation, wildfire management, and incorporation of Indigenous traditional ecological knowledge. They also emphasized the application of artificial intelligence/machine learning (AI/ML) for mapping and remote sensing tools.

Both Jake Slyder and Tim Assal described their respective government agency’s management of vast (mostly western) land areas and use of remote sensing for post-fire emergency stabilization and integration with the Assessment, Inventory, and Monitoring (AIM) program.

Kevin Butler offered more of a local perspective as he discussed land stewardship in Michigan. He emphasized the importance of community involvement and respecting natural ecosystems, especially fire-dependent ones, at the local level.

DAY TWO

The presentations on the second day of the workshop highlighted the opportunities that Earth observing satellite data presents for natural resource management applications. Five presenters contributed to the panel discussion, titled “Communicating and Soliciting End User Needs: Past, Present and Future.” The second – longer – block of breakout sessions also occurred with a short report-out at the end of the day. A poster session ran concurrently with the report-outs. While this session is not described in this report, it afforded participants an opportunity to showcase their Earth observation related projects and/or interact with their peers. Highlights from the day follow below.

Notable Presentations

Pontus Olafsson [NASA’s Marshall Space Flight Center] and Natasha Sadoff [NASA HQ—Satellite Needs Program Manager] presented on the Satellite Needs Working Group (SNWG), which provides a coordinated approach to identify and communicate federal satellite Earth observation needs and develop solutions based on Earth observation data. The speakers explained that as part of this effort, SNWG facilitates a biannual survey to all civilian federal agencies. SNWG provides federal agencies a path to coordinate Earth observing needs and a mechanism to develop actionable solutions for decision makers. Solutions cover thematic areas, including air quality, land use/land cover, and water resources. They noted that NASA is also making a greater effort to engage with agency partners in the co-development of new solutions that are useful, accessible, and actionable.

Alison York [University of Alaska Fairbanks] spoke about the Joint Fire Science Program (JFSP) and Fire Science Exchange Network (FSEN). JFSP’s main function is to maintain and grow a data repository and community based on fuels, fire behavior, fire ecology, and human dimensions. The goal is to help enable informed, actionable change by policy makers and land managers with the best available scientific support. York then discussed the FSEN, which acts as a mechanism to collate research needs from a collection of regional fire exchanges. The syntheses of data and data needs provides more effective understanding and management of fire.

Training Breakout Session Takeaways

On the second day, the four breakout sessions met, beginning with four short (25-minute) trainings. The speakers each gave half-hour presentations, which they repeated twice during the hour dedicated to the training breakouts, allowing participants to engage in two of the training breakouts if desired.

Pete Robichaud [USFS] discussed training opportunities for modeling post-fire hydrological response using the Water Erosion Prediction Project (WEPP). Soil burn severity is first assessed with remote sensing and then field verified. A subsequent soil burn severity map can be created to give details on physical features, e.g., ash color, ash depth, fine roots, soil structure, water repellency, and ground cover. This resource can be used to create a risk assessment table of probability and consequence parameters. Following the risk assessment, the Forest Service Water WEPP suite of tools can be used to model the landscape. The WEPP suite includes both hillslope and watershed modeling tools. The final step in the Burned Area for Emergency Response (BAER) program is to implement and monitor solutions.

Rupesh Shretha [Oak Ridge National Laboratory (ORNL), Distributed Active Archive Center (DAAC)] discussed the Earth Observing System Data and Information System (EOSDIS) DAACs, which are collocated with centers of science discipline expertise and archive and distribute NASA Earth Science data products. The ORNL DAAC archives and distributes terrestrial ecology data, particularly data from field and airborne campaigns. The Terrestrial Ecology Subsetting & Visualization Services (TESViS) – formerly MODIS–VIIRS subsets tool – provide subsets of satellite data in easy-to-use formats that are particularly valuable for site-based field research. The Ecological Spectral Information System (ECOSIS) integrates spectral data with measurements of vegetation functional traits (i.e., species, foliar chemistry). ECOSIS allows users to submit spectral data and return a citable DOIs. ECOSIS also provides users application programming interface (API)-based methods to retrieve thousands of field spectra.

Jake Slyder discussed the use of remote sensing for efficient resource management over vast tracts of land with limited human and financial resources. He explained that while the vast collection of remotely sensed data makes it challenging to effectively exploit, Google Earth Engine (GEE) has become an important tool in leveraging remotely sensed information to address BLM management questions. The Change and Disturbance Event Detection Tool (CDEDT), a GEE-based application, allows users to detect and develop vector geospatial products to identify changes and disturbances to surface cover between two dates of observations [10 m (~33 ft) resolution] from the European Space Agency’s (ESA) Copernicus Sentinel-2 mission. Slyder said that the Version 2 (V2) beta product includes the National Agriculture Imagery Program (NAIP) and ESA Copernicus Sentinel-1 SAR Imagery. CDEDT supports a range of BLM monitoring applications, including disaster events, energy development, forest disturbances, and seasonal patterns and processes (e.g., vegetation, water cover). The CDEDT tool is publicly available and does not require any license or special software.

DAY THREE

The third day was dedicated to the final block of the breakout sessions and a final plenary, where a representative from each breakout group gave five to seven minute summaries of their discussions throughout the meeting. The overview was followed by a meeting wrap-up and adjournment. The sections below summarize the topical presentations given on day three and encapsulate the three days of discussions.

Breakout Session A: Focus on Carbon

The carbon breakout aimed to inform participants about carbon-related EO initiatives and spark discussion about user needs.

Aaron Piña [USFS] spoke about the Forest Service’s broad base of applied research that spans wildfire weather and behavior to dynamics of the smoke produced – see Photo 2. Recent assessments have been made for wildland fire, controlled burn smoke, and remote air monitors. Piña spoke about Bluesky Playground, a community-driven tool aimed at providing the public with information on fuels and smoke modeling. These data have been used to identify important indicators for fires and fuels (e.g., vertical plume structure).

Piña then discussed a fusion Fire Radiative Power (FRP) data product [MOD19A2] that combines data from four sources – the Visible and Infrared Scanner (VIRS) on the former Tropical Rainfall Measuring Mission (TRMM), the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi National Polar-orbiting Partnership (Suomi NPP), the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra and Aqua platforms, and the Multi-Angle Implementation of Atmospheric Correction (MAIAC) aerosol product.

A group discussion followed Piña’s presentation, during which several participants expressed concerns about the continuity of VIIRS and the other observations that are used in the fusion FRP product. Another topic of discussion was the potential of remotely sensed data to improve the characterization of duff (decaying vegetation) in satellite data products. NASA’s Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission data have also been used to characterize the vertical structure of smoke plumes; however, these efforts have thus far been limited by personnel knowledge gaps as well as raw data formats.

Chris Woodall [USFS] discussed the growing emphasis on carbon metrics for a variety of sectors and applications. The USFS wants to work in tandem with other entities, especially federal organizations, to maximize efforts and workstream. USFS is seen as the in-situ carbon observer, while NASA is the remote sensor, and USGS is the lateral flux assessor. The coproduction of knowledge and data regarding carbon among these agencies is an iterative process. The USFS investment in improved Measurement, Monitoring, Reporting, and Verification (MMRV) of greenhouse gas (GHG), for example, can expand soil and land-use inventories to improve alignment with remote-sensing platforms. Challenges to implementing this cooperative approach to collecting carbon metrics include creating a workflow that incorporates a wealth of existing resources and accruing data from multiple federal agencies concerned with ecosystem carbon management to create scalable GHG knowledge. The coproduction, iteration, and dissemination of knowledge should be a major focus with all interested parties – not just the aforementioned federal agencies.

Sydney Neugebauer [NASA’s Langley Research Center] and Melanie Follette-Cook [GSFC] discussed NASA’s capacity building initiatives, which are aimed at developing and strengthening an organization or community’s skills, abilities, processes, and resources to enable them to survive, adapt, and thrive in a fast changing world. The DEVELOP, Indigenous Peoples Initiative, and SERVIR programs (all under the Earth Action program element) work towards capacity building through co-development projects, collaborative training, and data availability. The NASA Applied Remote Sensing Training (ARSET) program has offered over 100,000 training sessions since it was created in 2009 – primarily to international participants. The trainings are free and virtual for individuals interested in using remotely sensed data in a diverse suite of environmental applications. All content is archived. NASA’s Carnegie-Ames-Stanford Approach (CASA), which has contributed to global carbon dioxide (CO2) sequestration datasets for the past 30-years, will be upgraded to incorporate CO2 fluxes. The NASA cooperative interagency U.S. Greenhouse Gas Center is also looking for feedback on its beta portal.

The group discussions that followed identified and addressed AEOIP needs and questions (e.g., obtaining carbon and smoke emission estimates from prescribed wildfires and ensuring global satellite fire record continuity). Participants also identified the need for near real-time active fire and burned area mapping at medium scale and for continuity of these measurements. The group is interested in engaging federal agency end users to obtain feedback on their capacity to facilitate and elucidate capacity needs. Prominent challenges going forward include preparing for the end of the Terra and Aqua missions, which will include the decommissioning of MODIS, and ensuring the continuity of VIIRS, which is being used to allow for continuity of MODIS data products. One of the greatest unknowns identified was being able to determine wildfire fuel conditions in near-real time, and the ability to constrain estimates of fuel attributes to a focused fire event.

Andy Hudak discussed the diverse coalition of practitioners who manage more than just carbon (e.g., forest health, harvest, fires). Of the diverse group of stakeholders, Indigenous Tribes are at the cutting edge using lidar for carbon assessment. While Forest Inventory and Analysis plots are used for bias correction, they do not provide synoptic coverage for accurate carbon assessments. Lidar and other passive remote sensing satellite data provide a way to address this need. Tree lists are also highly valuable to carbon and forest managers for diverse applications. Application-specific metrics (e.g., timber volume, basal area, and density) can be weighted based on stakeholder priorities, as quantified from stakeholder surveys, to optimize data products.

Sarah Lewis [USFS] explained the needs and applications of Earth observations in a post-fire environment. The information needs to be available quickly, integrated into effective decision-making tools, and delivered in a functional product. Information is needed on water, soils, vegetation recovery, and habitat – all major metrics of interest in a data product. Areas of concern during post-fire management for water quality and erosion control include ash and soil–water transport. In addition, major concerns exist for timely data acquisition and processing, along with the fate and transport mapping of post-fire ash. Data products would benefit from end-user input to optimize relevance and accessibility of decision ready maps, models, and trusted recommendations.

The group identified the need for heavy carbon fuels and duff estimates for ecological modeling, which is critical to achieving a better understanding of smoke and carbon emissions. The heavy carbon fuel and duff estimates may be achieved through multiple means but may be most accessible currently through a new layer in the LANDFIRE database. They also identified the need for more post-fire data for model training and integration of active remote sensing data. Finally, the group identified the need for more regulation and research on prescribed fire emissions and disturbance.

Breakout Session B: Prescribed Fire

This breakout session focused on prescribed fires. Some of the major objectives and needs that emerged from this session were improved access to data, cultivating deeper public trust in the practice, creating networks of future coproduction, and assessing end-user needs, burn maps, and securing funding. The discussions emphasized knowledge and awareness gaps as a major impediment to prescribed fire implementation. Uniform capacity building is an ideal approach to engage stakeholders at a reference level appropriate to their background to optimize equity and efficacy.

Another issue that came up during discussion is that land management professionals do not have the time or resources to stay current with data sources and analysis techniques. The participants suggested the creation of a “Fire Science Library” as an iterative data tool to organize and present fire knowledge in an actionable and streamlined manner for public land managers. The interface would allow practitioners to filter unique categories (e.g., role, scope, region, ecosystem type, weather, agency affiliation) to provide the ability to search, modify, and maintain fire science knowledge as it evolves. This interface would also provide provenance through references to papers, justification for methods, and case studies. The library would guide and streamline data collection, analyses, and interpretation workflows that are needed for holistic prescribed fire planning and monitoring based on tangible needs from fire professionals.

The virtual library tool would provide a user with a fire-science knowledge graph, which is an organized representation of real-world entities and their relationships that could quickly connect fire-related management with current research questions concerning data products, processing methods, and data sources along with references and case studies. Information provided in the knowledge graph would need to be context specific but not overly prescriptive to avoid constraining users to a rigid workflow that is more common in basic data portals. Knowledge graphs are associated with semantic web technology that forms a modern version of a database. The tool establishes relationships between entities that promote new relationship discovery, search, and modification. It also provides a foundation on which other applications can be built, such as prescribed fires in the southeast and incorporating drone data. Focusing on prescribed fire may help to bound the initial product development but leave the door open for eventual expansion for wildfire.

The group identified objectives moving forward, including the need to finalize the main set of prescribed fire management questions (e.g., planning, implementation, pre/post monitoring), establish user personas based on known representatives and gaps, engage the Earth Science Information Partners (ESIP), identify cluster members (e.g., subject matter experts from local and federal agencies, private industry, and academia/research), and investigate additional funding sources. (Clusters are agile working groups within ESIP formed to focus on specific topics.)

Breakout Session C: Fractional Vegetation Cover

This breakout session focused on fractional vegetation cover (FVC) – see Photo 4. The presenters introduced three large FVC assessment efforts, and the participants contributed to a Strengths, Weakness, Opportunities, and Threats (SWOT) analysis of FVC products intended to improve the use of this data by decision makers – see Table.

Tim Assal discussed the BLM’s Assessment Inventory and Monitoring (AIM) strategy. He explained that AIM has nearly 60,000 monitoring locations across the terrestrial uplands, aquatic systems, and riparian and wetland habitat of the U.S., and the data collected are being used for monitoring and restoration activities. Assai added that integration of remote sensing data with field plot data enables the generation of continuous datasets (e.g., FVC that can relate field plot-level indicators to those based on remote-sensing). He also reported that FVC data are currently being used to address numerous management decisions.

Sarah McCord [USDA] discussed V3 of the Rangeland Analysis Platform (RAP). McCord explained that V3 uses vegetation cover and rangeland production data to monitor these parameters. The model also uses species composition data. She explained that there are approximately 85,000 training/validation locations across the U.S. that have been incorporated into the modeling process. She said that enhancements to future versions of RAP are expected as data from new satellite instruments, field plots, and deep learning (i.e., application of AI/ML techniques) are all incorporated into the model. McCord chairs a working group that is actively investigating sources of error and uncertainty within individual and across different FVC products.

Matt Rigge [USGS Earth Resources Observation and Science (EROS) Center] discussed V3 of the Rangeland Condition Monitoring Assessment and Projection (RCMAP), which will provide current and future condition using Landsat time series. Data available includes cover maps and potential cover. The platform uses various training data in addition to AIM plot data. In the future RCMAP plans to incorporate data from synthetic NASA-Indian Space Research Organization Synthetic Aperture Radar (NISAR), from NASA’s Earth Surface Mineral Dust Source (EMIT) mission, and from convolution neural network-based (CNN) algorithms.

Bo Zhou [University of California, Los Angeles (UCLA)] discussed V2 of the Landscape Cover Analysis and Reporting Tool (LandCART). V3 will be different and coming in the future. He explained that the BLM uses V3 to make legally defensible decisions. He then discussed the training data, which come mostly from AIM. The training dataset includes 71 Level-4 (L4) Ecoregions, as defined by the U.S. Environmental Protection Agency, with at least 100 observations. Zhou noted that these training data are used to define spatial extent, the temporal extent is defined by available satellite imagery, and uncertainty estimates are based on CNN and random forest (RF) machine-learning algorithms.

Eric Jensen [Desert Research Institute] discussed how ClimateEngine.org uses cloud-based tools, such as GEE, to access, visualize, and share Earth observation datasets to overcome computational limitations of big data in a real-time environment. It encompasses over 85 datasets, including RAP and RCMAP, and the group is working to add LandCART. Two core functionalities of the ClimateEngine app are producing maps and making graphs. Jensen provided a brief demonstration of the app using a juniper removal project in sage grouse habitat in southern Idaho.

Breakout Session D: Post-fire Effects and Recovery

This session focused on assessing, predicting, remediating, and monitoring areas in the aftermath of fires. The focus was on “shovel-ready” ideas, such as improving operational soil burn severity maps to connect post-fire ground conditions and soil properties. The participants highlighted the need to leverage information (e.g., active fire thermal data) to better detect changes in post-fire cover and soil properties. Such information would be beneficial to USFS’s Burned Area for Emergency Response (BAER) program as well as to researchers, data providers, decision makers, and community leaders. The group discussed steps that would aid in this collaboration (e.g., incorporating thermal imagery into mapping soil burn severity, developing and validating products, getting first-look data to field teams, monitoring threats by conducting rapid burn severity assessment before official soil burn severity maps are made available, and sharing outputs quickly with decision makers).

The breakout participants also noted the challenge of ash load mapping, which they suggested might be constrained by using information on pre-fire fuels (e.g., biomass, understory, and canopy vegetation) to constrain potential ash production. Derived information products [e.g., Normalized Difference Vegetation Index (NDVI), Leaf Area Index (LAI), LANDFIRE fuels layers, and RAP] may improve this process. The group noted the limitations of the VIIRS instrument for mapping fire duration and soil heating. The group proposed adding supplemental data through the use of National Infrared Operations (NIROPS) raw infrared imagery – see Figure 1.

Fire tools currently available – and under consideration for improving maps – include VIIRS active fire data through NASA’s Fire Information for Resource Management System (FIRMS), fire event tracking through NASA’s Earth Information System Fire Event Data Suite (FEDS), the burn severity prediction model at MTRI, and Rapid Differenced Normalized Burn Ratio Mapping at the University of Wisconsin, Madison. The group identified VIIRS L1 image capture to detect smoldering fires as a potential improvement in wildfire characterization. The group also suggested more frequent observations of moderate resolution satellites, GOES Integration [0.5–2 km (0.3–1.2 mi) spatial resolution], and comprehensive field data. They identified possible ways to improve post-fire soil burn severity maps (e.g., information on pre-fire fuels, soil characteristics, and thermal properties, such as fire heating, residence time, spread rate), optical characteristic (e.g., vegetation mortality, ash production), and lidar canopy metrics.

Presently, burn severity is assessed using a simple spectral index derived from remote sensing data, driven by necessity, data access, and computing power. The group presented the need to break this single number into ecologically meaningful components for better post-fire assessment and remediation. Improvements could involve incorporating additional information (e.g., peak soil temperature, heat residence time, and fuel moisture). Coupling atmospheric fire behavior models could address temporal gaps, necessitating high-spatial and temporal resolution thermal data sets.

The participants agreed that future strategies should include monitoring warmer areas and smoldering zones instead of just flaming fronts, as well as exploring temperature differences across burn severities. Additionally, post-fire assessments would benefit from using other spectral bands and post-fire Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) products. They also added that access to more field information is crucial for scientific post-fire observations. Efforts are underway to make the SBS S123 survey system a national standard, though surveys currently reside with local units that have good record-keeping practices.

Conclusion

The 2024 AEOIP workshop addressed a wide range of geospatial data tool and training needs and forums. The meeting centered on coproduction of knowledge and community-of-practice building as key needs for the geospatial data topics. Participants identified capacity building – through awareness, accessibility, and utility of data and tools – as the top priority for processing and technological advancement initiatives.

The breakout session topics selected (e.g., carbon concentrations, wildfires, prescribed fires, and landscape dynamics) were chosen to promote dialogue between data users and scientists, leading to plans for action and change in data and tool utility in four areas of interest for land managers. Following the meeting, the organizers submitted a spreadsheet detailing the data and tool needs identified during the breakouts to the Earth Action Program. The SNWG has also been made aware of the most compelling needs that participants identified. The AEOIP believes that by bridging two groups – data users and research and development – it will be possible to bolster user provenance and efficacy of NASA resources moving forward.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Media are invited to meet leaders in the space community during the 62nd annual Goddard Space Science Symposium, taking place from Wednesday, March 19, to Friday, March 21, at Martin’s Crosswinds in Greenbelt, Maryland. The symposium will also be streamed online.
      Hosted by the American Astronautical Society (AAS) in conjunction with NASA’s Goddard Space Flight Center in Greenbelt, the symposium examines the current state and future of space science and space exploration at large by convening leading minds across NASA, other government agencies, policy, academia, and industry – collectively navigating a path forward by identifying the opportunities and challenges ahead.
      This year’s theme, “Pathways and Partnerships for U.S. Leadership in Earth and Space Science,” highlights the evolving collaborative landscape between the public and private sectors, as well as how it is helping the United States remain and grow as a leading space power. 
      “Earth and space science are complex by nature, with a growing list of public and private enterprises carving out their space,” said Christa Peters-Lidard, co-chair of the symposium planning committee and Goddard’s director of sciences and exploration. “It’s an exciting time as we work to determine the future trajectory of space exploration in this new era, and the Goddard Space Science Symposium is an instrumental tool for gathering the insights of leading experts across a broad spectrum.”
      AAS President Ron Birk and Goddard Deputy Center Director Cynthia Simmons will deliver the symposium’s opening remarks on March 19, followed by panels on enabling science and exploration from the Moon to Mars and navigating space science and exploration policy. Greg Autry, associate provost for space commercialization and strategy at the University of Central Florida, will deliver the keynote address. The first day will conclude with an industry night reception.
      The second day of the symposium on Thursday, March 20, will feature panels on enhancing U.S. economic leadership through science, the Habitable Worlds Observatory, and the confluence of public science and the private sector. Gillian Bussey, deputy chief science officer for the U.S. Space Force, will serve as the luncheon speaker.
      Panels on the third and final day, March 21, will discuss integrating multi-sector data to advance Earth and space science, the Heliophysics Decadal Survey, and the space weather enterprise. Mark Clampin, acting deputy associate administrator for the NASA Science Mission Directorate, will provide the luncheon address.
      Media interested in arranging interviews with NASA speakers should contact Jacob Richmond, Goddard acting news chief.

      Summary of Special Engage Session on “Remote Sensing and the Future of Earth Observations”
      Introduction
      On October 16, 2024, a special session of the NASA Goddard Engage series took place in the Goett Auditorium (Building 3) at NASA’s Goddard Space Flight Center (GSFC). The Engage series is intended to explain work at GSFC in an immersive and nontechnical setting. GSFC’s Office of Communications, Earth Sciences Division, and Scientific Colloquium organized this special session.
      The featured speaker for this event was The Honorable Al Gore [former Vice President of the U.S.], who has a long history of advocating for the environment and raising public awareness of the worsening “climate crisis” – having received the Nobel Peace Prize for his efforts.
      The event also featured a panel discussion called “Remote Sensing and the Future of Earth Observations.” Three distinguished scientists spoke about what drew their interest in Earth science and responded to questions from the moderator and the in-person and online audience.
      Editor’s Note: This is not intended to be a comprehensive review of all NASA’s future plans regarding Earth Remote Sensing. Rather the panelists focused on some specific activities on which they had expertise that was intended to give a sense of the full suite of activities planned for the coming decade.
      While The Earth Observer typically does not usually report on Center-specific events, the newsletter makes an exception for this event because the former Vice President participated – and because the topic of the panel discussion is directly relevant to this publications’ wider audience. The remainder of this article summarizes the Engage session, including Gore’s remarks, the panel discussion, and the question-and-answer (Q&A) session that followed. A YouTube video of the full event is available for viewing.
      Opening Remarks
      Dalia Kirschbaum [GSFC—Director of Earth Sciences Division] welcomed the participants – both in-person and virtual. Casey Swails [NASA Headquarters—Deputy Associate Administrator] continued by thanking Gore for being one of most influential voices in the U.S. on climate . She said that Gore’s words and actions have inspired much more than just the Deep Space Climate Observatory (DSCOVR) mission. NASA – and GSFC in particular – has been conducting environmental studies since its beginning. She named historical missions, such as Vanguard, the Television Infrared Observation Satellite (TIROS), Landsat (partnership with U.S. Geological Service), and the Earth Observing System (EOS) – including more than 20 years of observations from the three Flagship Missions: Terra, Aqua, and Aura. (The Earth Observer’s Archives Page includes a “Bibliography of Articles with Historical Content” in which links to articles written on most of the missions mentioned in the previous sentence can be found.)
      Swails pointed out that GSFC is home to the largest population of Earth Scientists who produce more than 400 journal articles each year.
      “It will be you and your successors who will also make NASA (GSFC) the future of Earth observations,” said Swails. “You are continuing to accelerate core science research and enable action through the newly established Earth System Observatory project office, the Greenhouse Gas (GHG) project office, and new flagship missions, such as the Atmospheric Observing System (AOS) and Landsat Next.”
      On behalf of – at the time of the meeting – NASA Administrator Bill Nelson, Swails thanked Gore for participating in the Engage event, and she thanked all the scientists and engineers – past and present – that have led the way in making NASA (GSFC) a leader in Earth observations for more than six decades.
      Featured Speaker: The Honorable Al Gore
      Kirschbaum then introduced Al Gore – shown in Photo 1 – whom she described as an environmental advocate and a central figure in advancing public discourse on climate and sustainability. Following Gore’s many years of political service, he confronted the world with “An Inconvenient Truth,” a documentary on climate change that helped raise global awareness of the worsening state of Earth’s climate. For these efforts, Gore received the Nobel Peace Prize on October 12, 2007.
      Photo 1. Former U.S. Vice President Al Gore was the featured speaker at the Engage session on October 16, 2024. In addition to overall discussion of NASA’s Earth observing fleet and how Earth observations are used to investigate Earth’s changing climate, Gore’s remarks included reminiscences about his involvement in the Triana mission, which NASA canceled, then later revived and revised becoming known as DSCOVR – a NASA–NOAA partnership. See related article, “Summary of the 10th DSCOVR EPIC and NISTAR Science Team Meeting,” to learn more about DSCOVR and its scientific achievements over a decade in space. Photo credit: Travis Wohlrab [NASA’s Goddard Space Flight Center (GSFC)] Kirschbaum continued that Gore played a pivotal role in inspiring Triana , a NASA Earth science mission that would provide a near continuous view of Earth and measure Earth’s complete albedo while orbiting the first Sun–Earth Lagrange Point (hereinafter referred to as “the L1 point”). While Triana was canceled, the concept would live on and ultimately transition into the NASA–NOAA DSCOVR mission, which celebrates the 10th anniversary of its launch in February 2025. Gore made brief remarks at the opening session of the 10th DSCOVR Science Team meeting earlier in the day before coming to this meeting. A full “Summary of the 10th DSCOVR EPIC/ NISTAR Science Team Meeting” is published as a separate article in The Earth Observer.
      Gore began by thanking all who worked on DSCOVR and other missions at NASA and NOAA. He thanked Makenize Lystrup [GSFC—Center Director] and the team for welcoming him. He also acknowledged the DSCOVR project leaders from GSFC: Adam Szabo [DSCOVR Project Scientist (PS)], Alexander Marshak [DSCOVR Deputy PS], Jay Herman [Earth Polychromatic Imaging Camera (EPIC) Instrument Scientist], Richard Eckman [National Institutes of Health’s Advanced Radiometer (NISTAR) Instrument Scientist], and all those who worked on the mission.
      Gore reminisced about when the Triana mission was put into storage in 2001. He remembered his former Senate colleague, Barbara Mikulski [longtime MD Senator] assuring him that they would “feed [the satellite] space snacks” and take care of it until it was ready to use – which ultimately happened in 2008. He also acknowledged those who’ve worked on the DSCOVR mission since launch to extend its capabilities. He also recognized Francisco Valero [former Triana Principal Investigator] who was at University of California, San Diego’s Scripps Institute of Oceanography at the time, and was integral in championing the first iteration of this mission (i.e., Triana), as well as Alan Lazarus [Massachusetts Institute of Technology (MIT)—Research Scientist], who helped design DSCOVR’s solar particle sensor. (Jay Herman was also involved in Triana.) He also mentioned how Bill Nelson chaired the House Space Subcommittee contemporaneously to when Gore chaired the Senate Space Subcommittee.
      Gore acknowledged that DSCOVR is just one member of NASA’s fleet of Earth observing satellites – see Figure 1 er– plus those of domestic and international partners. What’s unique about DSCOVR, however, is its location – orbiting the L1 point, nearly one million miles (1.1 million km) away from Earth.
      Figure 1. [Top] NASA’s Earth Observing Fleet consists of over 20 satellite missions that, with one exception, continuously monitor our home planet from polar or low Earth orbit – including several installed on the International Space Station. The exception is the Deep Space Climate Observatory (DSCOVR) which orbits the first Earth–Sun Lagrange point in the Earth–Sun system [bottom], about 1 million mi (~1.1 million km) from Earth [bottom]. This gives the mission’s two Earth-observing instruments (EPIC and NISTAR) a unique vantage point for observing the full sunlit Earth. [Bottom] Some version of the placeholder diagram above showing DSCOVR orbiting the L1 point between Sun and Earth, 1 million miles from Earth.  Figure credit: TBD It can be argued that the modern environmental movement – which resulted in the development NASA’s Earth Observing System and other Earth observing missions – was inspired by a single image – “Earthrise,” which NASA Astronaut Bill Anders took of Earth on Christmas Eve 1968 during the Apollo 8 mission. The adage that “a picture is worth 1000 words” proved true in this instance as this single image changed how society viewed Earth, opening society’s awareness to the fragility and beauty of our home planet. Four years later, on Christmas Eve 1972, the first “Blue Marble” image was released, having been taken by Apollo-12 astronauts, as the spacecraft approached the Moon. (The image inspired subsequent “Blue Marble” images created using composites of satellite data.)
      Per the Wikipedia page linked above, “The [Blue Marble image] has been identified as one of the most widely publicized and influential images since its release – particularly in the advocacy for environmental protection.”
      Gore mentioned this in his remarks and stressed that this iconic image helped inspire the Triana/DSCOVR concept. This mission has helped scientists develop a more “complete picture” of Earth. He noted that today, DSCOVR/EPIC obtains a new “Blue Marble” (i.e. a full-disc image of Earth) every fifteen minutes – e.g., a set of images of Africa obtained on the 50th anniversary to mimic the original image from Apollo 12. Gore said that we learn so much about Earth from observing it from above (e.g., cloud dynamics, heating, vegetation, and the concentrations of ozone, sulfur dioxide, and particulate matter in the atmosphere). More than 100 peer-reviewed papers have been published on the unique science done at the L1 point by DSCOVR.
      Gore said that DSCOVR – along with the rest of NASA’s Earth observing fleet – has produced a treasure trove of information that makes it possible to make the invisible, visible. What was once a mystery can now be explained with scientific data. When DSCOVR was proposed in 1998, the scientific community was on the verge of a technological explosion via the Internet that would allow the collection, storage, processing, and display of untold mountains of information about Earth. It has now evolved even further with the advent of Artificial Intelligence (AI), leading to another potential information explosion just at the time when having such information is crucial.
      “We are in the midst of a violent collision between our current society’s organization and the surprisingly fragile ecological systems on which human flourishing depends,” said Gore.
      As the participants convened to celebrate the 10th anniversary of DSCOVR, he encouraged those present to think about how this data can be applied to address the incredible challenges of our generation – chief among them the Earth’s rapidly changing climate.
      “It’s hard to grapple with just how serious the [situation] is,” said Gore. However, he noted that, “Mother nature is a persuasive advocate. She has our attention!”
      He cited the two hurricanes – Helene and Milton – that impacted the U.S. in the weeks prior to this event. Despite the ever-present threat, Gore also pointed to the problematic “assault on funding” for science throughout the Federal budget. To address this need, Gore spoke of the growing need for private–public partnerships to address the imposing climate crisis.
      Gore discussed how Climate TRACE, the organization he cofounded, is harnessing NASA data and fusing it with other sources to pinpoint the sources of GHGs. Climate TRACE has determined the 500 million most relevant point sources, along with metadate (data describing the data). In essence, Climate TRACE seeks to reverse-engineer the GHG levels based on other environmental variables. He said that the newest Climate TRACE dataset will be released on November 14, 2024 at COP-29. Gore acknowledged that NASA [Jet Propulsion Laboratory (JPL)] contributes data and conducts analysis of data used in Climate TRACE.
      Quoting Lord Kelvin, Gore said, “you can only manage what you measure,” noting that our society has been having trouble managing global warming to date. However, thanks to organizations like NASA, our society is gaining the ability to measure it accurately.
      Gore then referenced John F. Kennedy’s famous speech at Rice University in 1961 that is most remembered for the line about “going to the Moon in this decade.” But in that speech Kennedy also said, “We set sail on this new sea, because there is new knowledge to be gained and new rights to be won. And they must be won and used for the progress of all people.”
      Gore applied this quote to the ongoing study of Earth’s climate. He said that our society is continuing to “sail on this new sea.” He gave kudos to all the people at NASA who are seizing all the opportunities to gather and reflect on “new knowledge” and apply it to issues directly relevant to societal flourishing.
      Gore concluded by saying that the DSCOVR mission is a great example of combining scientific discovery and public enlightenment. It has been incredibly successful, and he feels it should be extended, counting on scientists to expand our access to the knowledge we need to ensure the survival of human civilization.
      “If you ever doubt we have the political will to make changes,” said Gore, “just remember that political will is itself a renewable resource.”
      After a standing ovation from the audience, Kirschbaum thanked Gore for his remarks and his continued support of the Earth science community.
      Panel Discussion on the Future of Earth Science Remote Sensing
      Kirschbaum then transitioned to the panel discussion. She reflected on how we live with the impacts of climate every day – e.g., air quality impacting students, hurricanes impacting coastlines and coastal communities, shifting storm patterns impacting farmers.
      Since its inception in 1958, NASA has been a leader in studying Earth. The agency makes critical observations from space, aircraft, and the ground to understand climate change. NASA researchers integrate this information into climate models to understand the past, represent the present, and project the future state of our home planet.
      Kirschbaum said that today’s panel discussion focuses on the future. While questions remain, she emphasized that the agency works with partners on opportunities to do things differently and open new possibilities. She then introduced three NASA scientists, who also provide leadership beyond the walls of NASA.
      Miguel Román[GSFC Earth Sciences Division—Deputy Director for Atmospheres]; Lesley Ott [GSFC—Project Scientist for the U.S. Greenhouse Gas Center]; and John Bolten [GSFC—Chief of Hydrological Sciences Branch]. She asked each panelist – shown in Photo 2 – to start with by sharing a bit of their story with the audience to give some initial insights into their work and background on how they themselves became interested in studying climate.
      Photo 2. Following Gore’s remarks, there was a panel discussion entitled “Remote Sensing and the Future of Earth Observations.” Dalia Kirschbaum [GSFC—Director of Earth Sciences Division – left] moderated the discussion, directing questions to the three panelists seated to her right [left to right]: Miguel Román [GSFC Earth Sciences Division—Deputy Director for Atmospheres]; Lesley Ott [GSFC—Project Scientist for the U.S. Greenhouse Gas Center]; and John Bolten [GSFC—Chief of Hydrological Sciences Branch]. Photo credit: Travis Wohlrab Román began his career as an intern at NASA. After rising through the ranks, he left NASA to work in private industry before recently returning to GSFC. Originally from Puerto Rico, Román has been “inside the walls of a hurricane six times in his life.” He said that American citizens are increasingly experiencing what he experienced as a youth. He noted that two things happen when one in the middle of a hurricane – barometric pressure drops (ears pop) and there is a distinctive hissing sound.
      Román said the term hurricane is derived from a Taino word. He explained that in Puerto Rican folklore, Juracán (i.e., the “evil” Goddess of wind – especially hurricanes) was in opposition to Yucahu (i.e., the “good” God of creation, agriculture, peace, and tranquility).
      “The hissing winds of Juracán now reverberate across Florida, “ said Román—see Figure 2.

Colder temperatures (blues) are associated with the tops of high clouds, so the storm track stands out from the warmer temperature over the waters of the Gulf of Mexico.
      Figure credit: TBD
      He stressed that these winds are “different” – more intense – than the ones dealt with in the past. He added that we now have “land hurricanes” – called derechos, which are intense, widespread, and fast-moving lines of storms.
      Ott said that, in a sense, “science chose her.” She was raised by two scientists who met while studying physics. But she chose to study meteorology because it seemed to her to be the most ‘personal’ of the sciences. As Kirschbaum alluded to in her remarks earlier, weather impacts us all – physically and even emotionally. She loved this aspect of weather and wanted to understand the science behind the “air that we all swim in.”
      “Weather seems to be less in background and more on the ‘front page’ these days,” said Ott. “We regularly hear news stories about superstorms and devastating fires. We’re all increasingly impacted by extreme weather.”
      She also spoke about the ‘untold’ costs of climate change (e.g., lost school days, lost wages, not knowing if your home will survive a natural disaster), which has impacted how Ott practices meteorology. While she is a meteorologist, Ott doesn’t work on weather prediction. Instead, she uses the same kind of predictive models that are used for weather forecasting to focus on GHGs, which could help society navigate the realities of a changing planet.
      In her work, Ott tracks how climate changes – for better or worse. While the trend toward a warming world (climate) fuels more frequent and powerful extreme events (weather), e.g., heat waves, droughts, and storms, there are exceptions achieved through intentional human intervention – e.g., the recovery of the ozone hole (bought about through enforcement of the Montreal Protocol and its Amendments) and improvements of air quality. Both of these examples of positive change illustrate the value of international collaboration to address environmental issues. Ott said that research efforts can help to “track the future of the planet,” leading to more positive changes. Extending these positive changes to GHGs will help communities more effectively plan for and respond to a rapidly changing world.
      Bolten began by saying that he comes from Wood County WV and is the youngest of five boys. He could see the Ohio River from his kitchen window where he swam and canoed. Bolten explained that Wood County is in an area known as chemical valley, because a large number of chemical plants in the region provide important products for the world. These plants employ many of the people living in the region.
      Bolten’s father designed wastewater treatment systems for these chemical plants and passed along a deep appreciation of the impact humans can have on the environment. Similarly, Bolten spent many years enjoying the Ohio River and West Virginia wilderness, which instilled in him the value of protecting our freshwater resources. He grew up immersed in the environment and wanted to contribute to the greater good of society and make a positive difference in the world. He said that NASA is championing these same core values as an innovator and leader in Earth System Science. Bolten thanked Gore for spurring public discourse around climate.
      Question and Answer Session
      Kirschbaum began the Q&A session with several prepared questions followed by questions from both in-person and virtual participants – along with some more interspersed comments from the guest of honor.
      Kirschbaum posed the first question to Román: How do you see GSFC (NASA) advancements in tech and science helping us to predict extreme weather (e.g., heatwaves and hurricanes)?
      Román began his answer by stating that NASA’s EOS era is coming to an end – after more than two decades of observations. NASA’s EOS flagship missions – Terra, Aqua, and Aura – have each far exceeded their scheduled mission life. While scientists and engineers work together to extend the function as long as possible, practical realities (e.g., fuel supply, orbit decay) dictate that all the satellites must be decommissioned in the next few years. The EOS era has taught NASA and its partners many lessons about how to operate under what he described as “an accelerated set of extreme climate events.”
      “We simply could not have anticipated some of things we’re facing now when the EOS missions were designed,” said Ramon, citing the development of derechos and the rapid intensification of tropical cyclones.
      The EOS mission instrument teams developed a whole Earth observing technology toolbox on the fly. For example, scientists learned that while microwave sounders work well over water, these instruments face challenges over land due to surface emissivity variations. Infrared (IR) sounders, on the other hand, provide valuable data over all surfaces during clear conditions, but they can’t penetrate thick clouds. Investigators combined both measurements, producing a powerful tool for observing the changing Earth system and beginning to quantify the impact of those changes.
      While it is sad to see the EOS era end, Román said that NASA is entering an exciting new era where new technologies will allow for miniaturization of sounders. He also mentioned new observing technologies, such as the Hyperspectral Microwave Photonic Instrument (HyMPI) . The microwave sounders currently flying – which are part of NASA’s current Program of Record – retrieve atmospheric profiles with approximately 20 vertical layers. By contrast, HyMPI can produce as many as 1000 layers, offering enhanced thermodynamic sounding skill in the Earth’s planetary boundary layer (PBL) – the first 2 km (~1 mi) of the atmosphere – over conventional microwave sounders from the current Program of Record.
      Román emphasized that the PBL is an area that is still poorly observed and understood. This lowest level of the atmosphere is where humans and other plants and animals live – and where most climate impacts occur. It is thus vitally important to improve our understanding of the PBL. To emphasize this point, Román cited that one million stillbirths can be linked to tropospheric ozone pollution every year. The encouraging news is that NASA’s data can inform public health policy to help mitigate these harmful impacts.
      “The problem is an integrated one,” said Román, “and the Earth System Observatory (ESO) is designed for all of its missions to be integrated.”
      Román stressed that the climate challenges are complex, and ESO provides a model for all future campaigns to integrate many approaches to solve big problems.
      Kirschbaum directed the next question to Ott: As the NASA leader of the U.S. Greenhouse Gas Center, where do you see NASA making contributions?
      Ott responded that there has been tremendous innovation and advancement in the field of Earth observations over the past several decades – i.e., during the EOS era. As Al Gore alluded to in his earlier remarks, increasingly, this innovation comes from the pairing of private sector with the public data from satellites, aircraft campaigns, and ground networks that provide the infrastructure that companies need to test and improve new approaches.
      NASA has also played a foundational role in developing the systems approach to studying Earth. For example, half of human-produced emissions (sources) of carbon dioxide (CO2) are absorbed by vegetation and the ocean (sinks). It remains unclear how long this balance will continue, however. NASA aims to bring together different measurements of vegetation, ocean productivity, and gases in the atmosphere and make them readily available to the public. A wholistic approach to climate requires input from multiple satellites to successfully model changes in the concentration GHGs throughout the Earth system. To achieve this goal, the best from the government (e.g., NASA data) needs to merge with private industry to produce consistent long term data records that people can trust.
      Kirschbaum agreed that delivering trusted information and providing foundational datasets are core activities for NASA, and used that to segue to the next question, which she addressed to Bolten: NASA (GSFC) sits at the nexus of satellite observations and modeling. Where do you see progress of Earth Science to Action particularly in area of water quality?
      Bolten said that the first image of Earth was obtained 78 years ago in 1946. It happened somewhat by chance. Soldiers and scientists at White Sands Missile Range strapped a camera to a captured German V2 rocket, and they were fortunate to get a clear image of Earth. Fast forward to today, NASA has a fleet of more than 20 Earth-observing satellites – see Figure 1 [top] – that provide routine Earth observations. These data are vital for understanding our home planet, and for decision making. The observations from these satellites can be analyzed and used to inform decisions about Earth.
      The Electronic Numerical Integrator and Computer (ENIAC) was created the same year as the first Earth image. He noted that ENIAC took up an entire room. Today, his smart phone, which fits in his pocket, is more than 230 million times faster than ENIAC – driving home the point that technology has advanced beyond what most could imagine. Bolten also noted that 2024 is NASA’s Year of Open Science.
      Bolten said that his job focuses on food and water insecure areas, which often correlates with areas that lack data infrastructure. There is a vital need to strategically integrate open science and cloud-based services.
      “We can’t do this [work] in a bubble,” said Bolten. “We must work together.”
      Kirschbaum elevated a question from an attendee: There have been various climate change scenarios that have been offered as possibilities. Which one seems most likely to you to be correct?
      Ott explained that the worst- or best-case scenarios are usually outliers (i.e., the conditions in the “real world” typically lie somewhere in between the extremes). She commented that we’ve seen a large climate change investment from the Biden Administration. Those kinds of investments will have impact and have the power to change the trajectory for the future. Part of what NASA does is to show the world that the data we collect does make a tangible difference. That gives society reason for hope. The point of U.S. Greenhouse Gas Center is to bring together all these GHG observations in one place to analyze them and study them to show that we’re making progress on confronting this challenging issue. The objective is to create tangible evidence that, “when we take action, we can change things.”
      As if to underscore Ott’s point, Gore responded during her presentation that he believes that public choice does significantly impact how the future unfolds.
      “What we decide has consequences,” he said. 
      Gore is convinced the issue of our changing climate could be addressed if our society made up our collective mind to do it and then committed ourselves to take the decisive action needed to make that decision a reality in the near future.
       “The future is really up to us,” said Gore.
      The final three questions came from online participants.
      How can NASA improve its messaging?
      Bolten replied that this is a question that comes up repeatedly in the context of NASA outreach and communications. In the context of today’s discussion, he suggested the need to produce information that is not just useful but also usable (i.e., it can be applied in ways that directly benefit society). As an example, he pointed to the use of machine learning to model a flash flooding event in Ellicott City, MD (described in a 2020 article in Journal of Hydrometeorology) where waters rose from a normal levels to a devastating flash flood in about seven minutes – see Photo 3. Bolten continued that transparency, as well as connecting to people’s motivations, are keys to being more successful with NASA’s messaging.

      Román said that advances in forecasting on seasonal to sub-seasonal scales are key areas of focus for studies of Earth’s atmosphere. He noted that it is important to have observations and understand these observations to model events. For sub-seasonal prediction, we need to understand stratospheric dynamics and the chemistry going on in the upper troposphere and lower stratosphere.
      “Major fires and volcanic eruptions create massive changes in the atmosphere,” said Román. “We can’t see them like we can when we view a Landsat image.”
      One tool that could help us with sub-seasonal forecasting is the Stratosphere Troposphere Response using Infrared Vertically-resolved light Explorer (STRIVE) mission, which is one of four mission proposals for the first Earth System Explorer missions chosen for initial Phase A study. This mission aims to examine the interaction between the upper troposphere and the lower stratosphere. In particular, STRIVE will make observations of Earth’s limb (i.e., a narrow slice of atmosphere), which can help scientists gain insight into aerosol loading. According to Román, this data will be key to getting an accurate 30-day forecast. He referred to this information as the “holy grail” in terms of preparedness and resilience by improving early warnings for extreme weather. Some nations are limited to only using Doppler radar and if it fails, they are essentially blind to what is coming.
      Kirschbaum cited NASA’s AOS mission, which will be part of ESO, as another example of an important new measuring capability. This mission will represent the “next generation” for precipitations and aerosol observations. Scientists can use the data collected to understand how these phenomena interact with each other and with other atmospheric constituents to form storms.
      “AOS will be the baseline while STRIVE would be the bottom line,” concluded Román.
      What is the path forward to develop capacity for new observations while still maintaining high-quality, long-term time series and making the data accessible to the public?
      Ott cited the Carbon Mapper coalition as a current example where such a balance is being achieved/. Carbon Mapper made its first light images available to the public last week. This mission brings together a unique coalition of partners (including NASA/JPL and Planet, a private company) to develop and deploy two satellites with capabilities to detect and quantify methane (CH4) – e.g., see Figure 3 – and CO2 super-emitters at a level of granularity needed to support direct mitigation action.
      Figure 3. On December 4, 2024, the Tanager–1 satellite detected methane (CH4) plumes streaming downwind from oil and gas facilities in the Permian Basin (in west Texas and southeast New Mexico). This is one of more than 300 images of CH4 super-emitters from the oil and gas, coal, waste, and agriculture sectors across 25 countries that were released in February 2025. Tanager–1 launched in August 2024 and is the first satellite developed by the Carbon Mapper coalition between Planet (a private company) and NASA/Jet Propulsion Laboratory (JPL) and other partners. Planet owns, launched, and operates the satellite, which is equipped with technology from JPL. Figure credit: Carbon Mapper NASA’s investments in technology via its Earth Science Technology Office (ESTO) have enabled new airborne instruments that can be deployed in partnership with industry to demonstrate the quality of present-day satellite technologies and to provide a pathway toward next generation technologies. She stressed that the Federal government continues to play a crucial role in establishing standards and ensuring data integrity and continuity. NASA, for example, invests in ground-based systems and data services that help enable the commercial satellite industry. Long-term continuity of measurements is essential to connect new observations to existing ones. In this way, we can enable the continuing rise of NewSpace, while still providing foundational integrity and stability of the long-term climate data records that NASA and other Federal agencies maintain. This framework helps tie all the NewSpace endeavors together.
      Gore cited an example of a public–private partnership that happened in the past. He commented that in 1998 (the same year that Triana was proposed) he was also involved in proposal for Digital Earth. The guiding vision behind Digital Earth was to be able to hover over any point and drop down through successively more detailed layers. NASA contracted with a company called Keyhole, which Google acquired in the early 2000s. Gore raised this example to point out that Google Earth is the result of those initial efforts.
      Gore also connected this discussion to his work on Climate TRACE, which he had mentioned in his remarks earlier as a current example of public–private partnership. He stated that while we can see CH4 from space, the resolution is relatively low, i.e., a wide area must be scanned to get a CH4 measurement) and higher resolution is required to identify specific (or point) sources of CH4. Climate TRACE offers such higher resolution CH4 measurements, allowing researchers to focus more on identifying specific sources of pollution. By contrast the atmosphere is so enriched with CO2 that the signal-to-noise ratio is too high to measure the gas from space. For CO2 analysis, Climate TRACE uses AI to fuse together various images to allow CO2 to be detectable. The resulting measurements are precise enough to detect ripple ponds created by rotating fan blades.
      Closing Remarks
      Dalia Kirschbaum closed the meeting by thanking the guest of honor, Al Gore, once again for coming to the GSFC event. Gore not only spoke but was an active participant who demonstrated his knowledge of this subject area gained from years of experience working on climate issues. She quipped that “he’s the only former Vice President ever to use the Term signal-to-noise ratio correctly when talking to scientists.”.
      Kirschbaum also thanked everyone who participated in this event – including the over 800 online participants. While the discussions today offered numerous glimpses into the future of Earth remote-sensing observations, this information barely scratches the surface of all the work being carried out by scientists and engineers at NASA to make these plans a reality. She thanked all of those who work at NASA – who often put in long hours, quietly, behind the scenes without much recognition – for the work they do daily to enable NASA’s mission.

      How to Attend
      The workshop will be hosted by NASA Jet Propulsion Laboratory.
      Virtual and in-person attendance are available. Registration is required for both. (Link coming soon!)
      Virtual attendees will receive connection information one week before the workshop.
      Background, Goals and Objectives
      The NASA Engineering and Safety Center (NESC) is conducting an assessment of the state of cold capable electronics for future lunar surface missions. The intent is to enable the continuous use of electronics with minimal or no thermal management on missions of up to 20 years in all regions of the lunar surface, e.g., permanently shadowed regions and equatorial. The scope of the assessment includes: capture of the state of cold electronics at NASA, academia, and industry; applications and challenges for lunar environments; gap analyses of desired capabilities vs state of the art/practice; guidance for cold electronics selection, evaluation and qualification; and recommendations for technology advances and follow-on actions to close the gaps. The preliminary report of the assessment will be available the first week of April 2025 on this website, i.e., 3 weeks prior to the workshop. Attendees are urged to read the report beforehand as the workshop will provide only a limited, high-level summary of the report’s key findings. The goal of the workshop is to capture your feedback with regards to the findings of the report, especially in the areas below: Technologies, new or important studies or data that we missed. Gaps, i.e. requirements vs available capabilities that we missed. Additional recommendations, suggestions, requests, that we missed.
