We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

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.

Featured Air Quality Observation Method: TEMPO
NASA's Tropospheric Emissions: Monitoring Pollution (TEMPO) instrument provides hourly measurements of O3, NO2, and other key elements of air pollution.
These new Tropospheric Emissions: Monitoring of Pollution (TEMPO) products will aid validation efforts and algorithm development, and will be used to expand the mission’s higher-level products.
5 MIN READ
This webinar provides an overview of the TEMPO mission and its data products and shows how to discover and access TEMPO data products using NASA's Earthdata Search.
The 14 layers from the Tropospheric Emissions: Monitoring of Pollution mission offer data on clouds, nitrogen dioxide, ozone, and more.
The beta release of Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission data products lets users begin developing applications using these data.
