    • TROPESS CrIS-SNPP L2 Ammonia for West Coast Fires, Standard Product V1 (TRPSDL2NH3CRSWCF) at GES DISC

    Metadata Updated: September 18, 2025

    The TROPESS CrIS-SNPP L2 Ammonia for West Coast Fires, Standard Product contains the vertical distribution of the retrieved atmospheric state of ammonia (NH3), formal uncertainties, and diagnostic information measured by the CrIS instrument on the Suomi-NPP satellite. This product focuses on the CONUS region (20N-60N; 150W-40W) for the time period from 2020-08-01 to 2020-10-31, during the outbreak of U.S. West Coast wildfires. The NASA TRopospheric Ozone and Precursors from Earth System Sounding (TROPESS) project, uses an optimal estimation algorithm, known as the MUlti-SpEctra, MUlti-SpEcies, Multi-SEnsors (MUSES).The data files are written in the netCDF version 4 file format, and each file contains one day of data. The data have a spatial resolution of 14 km (CrIS nadir FOV), and are reported at 15 vertical levels from the surface to 0.1 hPa. The principal investigator for the TROPESS project is Kevin W. Bowman.
