New TEMPO Cosmic Data Story Makes Air Quality Data Publicly Available
On May 30th, 2024, NASA and the Center for Astrophysics | Harvard & Smithsonian announced the public release of “high-quality, near real-time air quality data” from NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) mission. The NASA Science Activation program’s Cosmic Data Stories team, led by Harvard University in Cambridge, MA, has since released a new “Data Story” – an interactive, digital showcase of new science imagery, including ideas for exploration and scientific highlights shared in a brief video and narrative text – that provides a quick and easy way for the public to visualize this important, large data set from TEMPO.
TEMPO allows unprecedented monitoring of air quality down to neighborhood scales, with its hourly daytime scans over North America. Air pollutants like NO2, produced, for example, by the burning of fossil fuels, can trigger significant health issues, especially among people with pre-existing illnesses such as asthma. The interactive views in the TEMPO Data Story provide public access to the same authentic data that scientists use and invite the public to explore patterns in their local air quality. For example, how do NO2 emissions vary in our area throughout the day and week? What are possible sources of NO2 in our community? How does our air quality compare with that of other communities with similar population densities, or with nearby urban or rural communities? TEMPO’s hyper-localized data will allow communities to make informed decisions and take action to improve their air quality.
The Cosmic Data Story team is grateful to TEMPO scientists, Xiong Liu and Caroline Nowlan, for providing the team with early access to the data and guidance on NO2 phenomena that learners can explore in the data. The TEMPO Data Story, featured on TEMPO’s webpage for the public, adds Earth science data to the portfolio of Cosmic Data Stories that is already making astrophysics data accessible to the public.
TEMPO Team Atmospheric Physicist from the Harvard-Smithsonian Center for Astrophysics, Caroline Nowlan, had this to say: “TEMPO produces data that are really useful for scientists, but are also important for the general public and policy makers. We are thrilled that the Cosmic Data Stories team has made a tool that allows everyone to explore TEMPO data and learn about pollution across North America and in their own communities.”
The Cosmic Data Stories project is supported by NASA under cooperative agreement award number 80NSSC21M0002 and is part of NASA’s Science Activation Portfolio.

A view from the TEMPO Data Story, shows TEMPO’s NO2 data overlaid on a map of North America. A large plume of NO2, caused by large wildfires, arcs from Northern California all the way to Idaho. Other “hot spots” of NO2 are seen over cities across the US, Canada, and Mexico. Users can view any available date, as well as explore some featured dates and locations that describe phenomena of interest that are visible in the data. Share

A proposal entitled, “TEMPO-EMIT synergy: Enhancing applications of GHG (greenhouse gas) and air pollutant observations over key emission sources,” was selected for funding through a NASA cross-mission product opportunity. The project, co-led by Aaron Naeger at SPoRT, will integrate the complementary air pollutant and GHG data from the NASA TEMPO and EMIT missions for designing a TEMPO-EMIT merged product concept, which aims to facilitate assessments of GHG and co-pollutant emissions from key source regions in the U.S. The focus of this project will be on the oil and gas operations in the Permian Basin where recent data have indicated strong nitrogen dioxide and methane emissions from the facilities. The National Park Service and air agencies have a high-level of interest in better understanding emissions from these facilities for improving air quality management in the region.

4 Min Read NASA, EPA Tackle NO2 Air Pollution in Overburdened Communities
This map shows average concentrations of nitrogen dioxide for 2022 over the U.S., as detected by the Ozone Monitoring Instrument on NASA’s Aura satellite. Higher concentrations are in red and purple. Lower concentrations are in blue. Credits:
NASA’s Scientific Visualization Studio Earth (ESD) Earth Home Explore Climate Change Science in Action Multimedia Data For Researchers For the first time, NASA data about nitrogen dioxide (NO2), a harmful air pollutant, is available in the Environmental Protection Agency’s (EPA) widely used Environmental Justice Screening and Mapping Tool (EJScreen). This update marks a crucial step in addressing air quality disparities in overburdened communities across the United States.
“Having access to this accurate and localized NO2 data allows organizations like ours to understand the air quality challenges we encounter, and to advocate more effectively for the health and well-being of community residents,” said Samuel Jordan, president of the Baltimore Transit Equity Coalition.
Previously, EJScreen included data on ozone, fine particulate matter, and various other environmental hazards. But it lacked information on NO2, which has been linked to respiratory issues such as asthma, especially in children.
“Incorporating NO2 data into EJScreen is a testament to how NASA’s Earth science capabilities can be applied to address crucial societal challenges,” said John Haynes, NASA’s program manager for Health and Air Quality. “This collaboration with the EPA underscores our commitment to using space-based observations to benefit public health and environmental justice.”
NO2 is emitted by burning fossil fuels and contributes to the formation of surface ozone. Communities of color and lower-income populations often live closer to highways, factories, transportation hubs, and other NO2 sources than their wealthier counterparts. As a result, residents are exposed to higher levels of this air pollutant and others, exacerbating health inequalities.
For example, a new NASA-funded study used satellite data and other information to show that nearly 150,000 warehouses in the U.S. increase local NO2 levels and are predominantly located in marginalized communities. The findings reveal a 20% increase, on average, in near-warehouse NO2, linked to truck traffic and warehouse density.
“NO2 is very short-lived in the air, and so its levels are high in the area where it is emitted,” said Gaige Kerr, study coauthor and an air pollution researcher at George Washington University in Washington, who was involved in incorporating NASA’s NO2 data into EJScreen. “This tool democratizes access to high-quality NO2 data, allowing individuals without a background in data analysis or data visualization to access and understand the information easily.”
EJScreen uses data from the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite and computer models to provide average annual NO2estimates at the census block level, revealing the amount of chronic surface-level NO2 that people may be exposed to in their neighborhoods.
“Satellite data has the potential to transform the measurement of certain environmental and climate factors,” said Tai Lung, an environmental protection specialist with EPA and EJScreen lead. “The consistency of NASA’s NO2 data for every corner of the U.S. makes it tremendously valuable for screening and mapping of disproportionate impacts in communities.”
The dataset was developed with contributions from George Washington University, the University of Washington School of Medicine in Seattle, and Oregon State University in Corvallis. The data integration was made possible through a NASA grant to the Satellite Data for Environmental Justice Tiger Team (part of NASA’s Health and Air Quality Applied Sciences Team), which worked closely with the EPA to ensure the data’s accuracy and relevance.
NASA uses a variety of instruments on satellites, aircraft, and ground stations to continually gather data on key air pollutants. Scientists supported by NASA and other researchers monitor the origins, levels, and atmospheric movement of these pollutants. Their research offers crucial Earth-observation data that can guide air quality standards, shape public policies, and inform government regulations, ultimately aiming to enhance economic and human welfare.
The Aura satellite recently celebrated its 20-year anniversary. In the future, Kerr said, the team could explore using NO2 data from NASA’s new TEMPO (Tropospheric Emissions: Monitoring of Pollution) instrument on the Intelsat commercial satellite.
TEMPO launched in 2023 and offers hourly daytime measurements, rather than OMI’s once-daily measurements. This capability could further enhance the EPA tool, providing insight on pollution levels throughout the day and supporting proactive air pollution management.
