NASA’s Earth Observatory United States embassies and consulates, along with American citizens traveling and living abroad, now have a powerful tool to protect against polluted air, thanks to a collaboration between NASA and the U.S. State Department.
Since 2020, ZephAir has provided real-time air quality data for about 75 U.S. diplomatic posts. Now, the public tool includes three-day air quality forecasts for PM2.5, a type of fine particulate matter, for all the approximately 270 U.S. embassies and consulates worldwide. These tiny particles, much smaller than a grain of sand, can penetrate deep into the lungs and enter the bloodstream, causing respiratory and cardiovascular problems.
“This collaboration with NASA showcases how space-based technology can directly impact lives on the ground,” said Stephanie Christel, climate adaptation and air quality monitoring program lead with the State Department’s Greening Diplomacy Initiative. “This is not something the State Department could have done on its own.” For instance, placing air quality monitors at all U.S. diplomatic posts is prohibitively expensive, she explained.
“NASA’s involvement brings not only advanced technology,” she added, “but also a trusted name that adds credibility and reliability to the forecasts, which is invaluable for our staff stationed abroad.”
The forecasts, created using NASA satellite data, computer models, and machine learning, are crucial for U.S. embassies and consulates, where approximately 60,000 U.S. citizens and local staff work. Many of these sites are in regions with few local air quality monitors or early warning systems for air pollution.
“ZephAir’s new forecasting capability is a prime example of NASA’s commitment to using our data for societal benefit,” said Laura Judd, an associate program manager for Health and Air Quality at NASA. “Partnering with the State Department allows us to extend the reach of our air quality data, providing embassies and local communities worldwide with vital information to protect public health.”
Enhancing Health, Safety with NASA Air Quality Data
To manage air pollution exposure, the tool can assist diplomatic staff with decisions on everything from building ventilation to outdoor activities at embassy schools.
For many embassies, especially in regions with severe air pollution, having reliable air quality forecasts is crucial for safeguarding staff and their families, influencing both daily decisions and long-term planning. “Air quality is a top priority for my family as we think about [our next assignment], so having more information is a huge help,” said Alex Lewis, a political officer at the U.S. embassy in Managua, Nicaragua.

U.S. Department of State Previously, ZephAir only delivered data on current PM2.5 levels using air quality monitors on the ground from about 75 U.S. diplomatic locations and about 50 additional sources. Now, the enhanced tool provides PM2.5 forecasts for all sites, using the Goddard Earth Observing System forward processing (GEOS-FP), a weather and climate computer model. It incorporates data on tiny particles or droplets suspended in Earth’s atmosphere called aerosols from MODIS (Moderate-resolution Imaging Spectroradiometer) on NASA’s Terra and Aqua satellites.
Aerosols are tiny airborne particles that come from both natural sources, like dust, volcanic ash, and sea spray, and from human activities, such as burning fossil fuels. PM2.5 refers to particles or droplets that are 2.5 micrometers or smaller in diameter — about 30 times smaller than the width of a human hair.
“We use the GEOS-FP model to generate global aerosol forecasts,” said Pawan Gupta, of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the lead scientist on the project. “Then we calibrate the forecasts for embassy locations, using historical data and machine learning techniques.”
As of August 2024, the forecasting feature is available on the ZephAir web and mobile platforms.
The new forecasts are about more than just protecting U.S. citizens and local embassy staff; they are also contributing to global action on air quality. The State Department engages with local governments and communities to raise awareness about air quality issues. “These forecasts are a critical part of our strategy to mitigate the impacts of air pollution not only for our personnel but also for the broader community in many regions around the world,” Christel said.
Officials with the Greening Diplomacy Initiative partnered with NASA through the Health and Air Quality Applied Sciences Team to develop the new forecasts and will continue the collaboration through support from the Satellite Needs Working Group.
Looking ahead, the team aims to expand ZephAir’s capabilities to include ground-level ozone data, another major pollutant that can affect the health of embassy staff and local communities.

The stars in the big Wyoming skies inspired Aaron Vigil as a child to dream big. Today, he’s a mechanical engineer working on the Solar Array Sun Shield (SASS) for the Nancy Grace Roman Space Telescope at Goddard.
Name: Aaron Vigil
Title: Mechanical Engineer
Formal Job Classification: Aerospace Technology, Flight Structures
Organization: Mechanical Engineering, Engineering and Technology Directorate (Code 543)
Aaron Vigil is a mechanical engineer at Goddard Space Flight Center in Greenbelt, Md. Photo courtesy of Aaron Vigil What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?
I currently work on the Solar Array Sun Shield (SASS) for the Nancy Grace Roman Space Telescope. I support daily integration and testing tasks related to the SASS assembly. I spend a lot of my time working with Goddard mechanical technicians and other engineers to execute test plans and procedures to assemble, test, and integrate SASS hardware.
What interests you about space?
I grew up in rural Wyoming. I did a lot of hiking, hunting, fishing, and camping. We were on the mountains constantly. I remember being up at night, sitting around the campfire with my family, looking up at the stars.
I was fascinated and captivated! I wanted to learn more about space.

In 2019, I began a B.S. in mechanical engineering at the University of Wyoming in Laramie.
In the spring of 2020, I reached out to an organization at the University of Wyoming looking for opportunities to further my education in the field of aerospace. They introduced me to the Wyoming Space Grand Consortium and, through their website, I learned of and applied to be a NASA Office of STEM Engagement intern in the spring of 2021. I received an offer and, in the summer of 2021, began working as a remote intern at Goddard on the 3D modeling and rendering of early spacecraft.
How did the Hispanic Advisory Committee for Employees (HACE) introduce you to the Pathways Program?
The summer of 2021, the different employee advisory committees at Goddard held presentations for the interns. I am Hispanic; I naturally gravitated towards HACE and fell in love with the extremely warm community they provided.
I attended their monthly meetings and I presented to the center at their end of the summer intern presentation. HACE introduced me to the Pathways Program, and the organization was instrumental in my becoming a Pathways student intern. This Pathways internship eventually led to my conversion to a fulltime employee and my current position in the Mechanical Engineering Branch here at Goddard.
What one piece of advice would you give to a new intern?
Never be afraid to ask questions and always seek out new connections. Goddard is a well of knowledge, you can learn and grow a lot from those around you.
Tell us about your mentorship at Goddard.
Jack Marshall is an aerospace engineer and the lead for SASS. When I was an intern, he showed me a glimpse into the world of engineering, providing perspective on all aspects of the project from administrative to technical. He continues to guide my engineering journey and has been instrumental in developing me into the engineer I am today. I am incredibly grateful to Jack for his welcome and his guidance.
What is the coolest part about your job?
The best parts about my job are the people I get to work with and the hardware we get to build. Whether we’re in a small lab in Goddard’s integration and testing facility or a large clean room, I get to spend most of my days working with incredible people to build, test, and integrate flight hardware. Every day there is something to be excited about and someone I get to work with who is likely to teach me something new. That excitement makes my work fun.
It’s also fun to work in facilities like the largest clean room at Goddard, where the James Webb Space Telescope was built. It was interesting getting used to being gowned up. You start with removing electronics and putting on a face mask, hair net, and shoe covers, before taking a quick air shower. Next comes the hood, coveralls, and boots, before taping your gloves and finally entering the clean room.

I would hope to have the opportunity to continue learning and working here at Goddard. I love what I do, and I hope to help others interested, find a similar path to NASA.
What do you do fun?
I still love to go fishing and hiking any chance I get and have been looking forward to doing more here in Maryland. Since moving to the area, I have also been enjoying attending Nationals baseball games in D.C., and I have been looking for opportunities to continuing to play music since graduating college.

My biggest inspirations have been my parents and grandparents, without them I would not be where I am today. I cannot thank them enough. They provided me my foundation and have supported me throughout my life, encouraging me to never give up. They have always had my back.
I also want to thank my Wyoming community where I grew up and my early mentors within that community.

This view of Jupiter was captured by the JunoCam instrument aboard NASA’s Juno spacecraft during the mission’s 62nd close flyby of the giant planet on June 13. Citizen scientist Jackie Branc made the image using raw JunoCam data.Image data: NASA/JPL-Caltech/SwRI/MSSS. Image processing: Jackie Branc (CC BY) Using data from the Advanced Stellar Compass (ASC) star tracker cameras aboard NASA’s Juno, this graphic shows the mission’s model for radiation intensity at different points in the spacecraft’s orbit around Jupiter.NASA/JPL-Caltech/DTU Using cameras designed for navigation, scientists count ‘fireflies’ to determine the amount of radiation the spacecraft receives during each orbit of Jupiter.
Scientists with NASA’s Juno mission have developed the first complete 3D radiation map of the Jupiter system. Along with characterizing the intensity of the high-energy particles near the orbit of the icy moon Europa, the map shows how the radiation environment is sculpted by the smaller moons orbiting near Jupiter’s rings.
The work relies on data collected by Juno’s Advanced Stellar Compass (ASC), which was designed and built by the Technical University of Denmark, and the spacecraft’s Stellar Reference Unit (SRU), which was built by Leonardo SpA in Florence, Italy. The two datasets complement each other, helping Juno scientists characterize the radiation environment at different energies.
Both the ASC and SRU are low-light cameras designed to assist with deep-space navigation. These types of instruments are on almost all spacecraft. But to get them to operate as radiation detectors, Juno’s science team had to look at the cameras in a whole new light.
“On Juno we try to innovate new ways to use our sensors to learn about nature, and we have used many of our science instruments in ways they were not designed for,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. “This is the first detailed radiation map of the region at these higher energies, which is a major step in understanding how Jupiter’s radiation environment works. This will help planning observations for the next generation of missions to the Jovian system.”
Counting Fireflies
Consisting of four star cameras on the spacecraft’s magnetometer boom, Juno’s ASC takes images of stars to determine the spacecraft’s orientation in space, which is vital to the success of the mission’s magnetic field experiment. But the instrument has also proved to be a valuable detector of high-energy particle fluxes in Jupiter’s magnetosphere. The cameras record “hard radiation,” or ionizing radiation that impacts a spacecraft with sufficient energy to pass through the ASC’s shielding.
“Every quarter-second, the ASC takes an image of the stars,” said Juno scientist John Leif Jørgensen of the Technical University of Denmark. “Very energetic electrons that penetrate its shielding leave a telltale signature in our images that looks like the trail of a firefly. The instrument is programmed to count the number of these fireflies, giving us an accurate calculation of the amount of radiation.”
Jupiter’s moon Europa was captured by the JunoCam instrument aboard NASA’s Juno spacecraft during the mission’s close flyby on Sept. 29, 2022.Image data: NASA/JPL-Caltech/SwRI/MSSS. Image processing: Björn Jónsson (CC BY 3.0) Because of Juno’s ever-changing orbit, the spacecraft has traversed practically all regions of space near Jupiter.
ASC data suggests that there is more very high-energy radiation relative to lower-energy radiation near Europa’s orbit than previously thought. The data also confirms that there are more high-energy electrons on the side of Europa facing its orbital direction of motion than on the moon’s trailing side. This is because most of the electrons in Jupiter’s magnetosphere overtake Europa from behind due to the planet’s rotation, whereas the very high-energy electrons drift backward, almost like fish swimming upstream, and slam into Europa’s front side.
Jovian radiation data is not the ASC’s first scientific contribution to the mission. Even before arriving at Jupiter, ASC data was used to determine a measurement of interstellar dust impacting Juno. The imager also discovered a previously uncharted comet using the same dust-detection technique, distinguishing small bits of the spacecraft ejected by microscopic dust impacting Juno at a high velocity.
Dust Rings
Like Juno’s ASC, the SRU has been used as a radiation detector and a low-light imager. Data from both instruments indicates that, like Europa, the small “shepherd moons” that orbit within or close to the edge of Jupiter’s rings (and help to hold the shape of the rings) also appear to interact with the planet’s radiation environment. When the spacecraft flies on magnetic field lines connected to ring moons or dense dust, the radiation count on both the ASC and SRU drops precipitously. The SRU is also collecting rare low-light images of the rings from Juno’s unique vantage point.
“There is still a lot of mystery about how Jupiter’s rings were formed, and very few images have been collected by prior spacecraft,” said Heidi Becker, lead co-investigator for the SRU and a scientist at NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission. “Sometimes we’re lucky and one of the small shepherd moons can be captured in the shot. These images allow us to learn more precisely where the ring moons are currently located and see the distribution of dust relative to their distance from Jupiter.”
More About the Mission
NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Juno mission for the principal investigator, Scott Bolton, of the Southwest Research Institute in San Antonio. Juno is part of NASA’s New Frontiers Program, which is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington. The Technical University of Denmark designed and built the Advanced Stellar Compass. The Stellar Reference Unit was built by Leonardo SpA in Florence, Italy. Lockheed Martin Space in Denver built and operates the spacecraft.
