Air Quality Data Access and Tools

NASA has air quality datasets that help researchers characterize the particular makeup of the air we breathe. Access a range of data and data tools such as AppEEARS, FIRMS, and Giovanni to make the most of air quality data.

Air quality comprises a constellation of scientific topics that inform our understanding of this field. Learn more about data and resources focused on aerosol optical depth, aerosol index, trace gases, land surface reflectance, the effect of dust, ash, and smoke, and human dimensions, including natural hazards.

Many NASA observation methods—platforms, instruments, and space geodesy techniques—provide data that improve our understanding of air quality, including NASA's Tropospheric Emissions: Monitoring Pollution (TEMPO) instrument, featured below. Learn more about how the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Harmonized Landsat Sentinel-2 (HLS), Moderate Resolution Imaging Spectroradiometer (MODIS), and Visible Infrared Imaging Radiometer Suite (VIIRS) continually acquire data about pollutants.
