NASA Mission Monitoring Air Quality from Space Extended

The TEMPO mission detects and highlights movement of smoke originating from fires burning in Manitoba on June 2, 2025. Seen in purple hues are observations made by TEMPO in the ultraviolet spectrum compared to Advanced Baseline Imagers (ABIs) on NOAA’s GOES-R series of weather satellites that do not have the needed spectral coverage. The NOAA GOES-R data paired with NASA’s TEMPO data enhance state and local agencies’ ability to provide near-real-time smoke and dust impacts in local air quality forecasts.

Since launching in 2023, NASA’s Tropospheric Emissions: Monitoring of Pollution mission, or TEMPO, has been measuring the quality of the air we breathe from 22,000 miles above the ground. June 19, 2025, marked the successful completion of TEMPO’s 20-month-long initial prime mission, and based on the quality of measurements to date, the mission has been extended through at least September 2026. The TEMPO mission is NASA’s first to use a spectrometer to gather hourly air-quality data continuously over North America during daytime hours. It can see details down to just a few square miles, a significant advancement over previous satellites.
