TROPOMI Near Real-Time Data

Near real-time atmospheric radiance and composition data from the European Space Agency TROPOspheric Monitoring Instrument (TROPOMI) are available through NASA’s Land, Atmosphere Near real-time Capability for Earth observation (LANCE).

Launched in 2017, the TROPOspheric Monitoring Instrument (TROPOMI) aboard the Copernicus Sentinel-5 Precursor (S5P) satellite provides measurements of hyperspectral radiances from the UV to Near IR that can be used to retrieve atmospheric composition and aerosol properties. Near real-time (NRT) TROPOMI data are available through NASA’s Land, Atmosphere Near real-time Capability for Earth observation (LANCE) generally within 30 to 180 minutes of satellite observation. TROPOMI is a key tool for the atmospheric radiation, aerosol/plume forecasting, and air quality community.
