The TROPESS CrIS-SNPP L2 Ammonia for Australian 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 Australia region (60S-0S; 100E-177.5E) for the time period from 2019-11-01 to 2020-01-31, during the outbreak of Austrailan 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.
