Near real-time (NRT) tropospheric pollution data from the Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument are available through NASA’s Land, Atmosphere Near real-time Capability for Earth observation (LANCE) webpage, in addition to other ESDIS data distribution channels and platforms.
Launched in 2023, the TEMPO instrument is deployed on a commercial geostationary satellite located about 22,000 miles above Earth’s equator at 91.0 West longitude. TEMPO makes hourly observations of tropospheric pollution, including nitrogen dioxide (NO2) and formaldehyde (H2CO) across Greater North America.
With its multi-spectral capabilities, TEMPO characterizes the boundary layer, as well as free tropospheric and stratospheric ozone. These unique measurement capabilities also allow for the retrieval of aerosol and cloud parameters. TEMPO NRT data are used to monitor real-time air quality conditions and track transport of pollution across North America. These data are a key tool for the atmospheric science and air quality management community.
Near Real-Time (NRT) TEMPO data are available through NASA’s LANCE generally within 180 minutes of satellite observation. They are funded by the Satellite Needs Working Group (SNWG).
