New research based on NASA data shows potential for satellites to monitor air pollution
July 8, 2026
“Today, peer-reviewed journal GeoHealth published two research studies that show how data from NASA satellites in space can help people better understand local air quality on the ground. Specifically, the studies examine the use of satellite-derived estimates of fine particulate matter (PM2.5) to complement the existing U.S. air quality monitoring network and quantify particle pollution in counties where there are no air quality monitors. This is significant because nearly 80% of counties do not have ground-based monitors for particle pollution. The reports’ authors are leading air quality experts from the University of Wisconsin–Madison, Washington University in St. Louis and the American Lung Association.”
