Explore Air Quality with NASA
Where Does NASA Fit?
NASA instruments — on satellites, planes, and the ground — constantly collect data on air quality. NASA-funded scientists track the sources and concentrations of major pollutants and their movement through the atmosphere. They provide managers and policymakers with Earth observations that can inform decisions around air quality for economic and human benefit.

How NASA Sees the Air We Breathe
NASA and NOAA, among other agencies, worked together this summer through the STAQS and AEROMMA missions to calibrate and validate NASA’s new TEMPO satellite. The satellite and missions combined aim to not only better measure air quality, and the major pollutants that impact it, but also to improve air quality, from street to stratosphere. This effort was documented during the August 2023 campaign leg, which took place over the Chicago region.
