The TROPESS CrIS L2 Ozone for Reanalysis Stream, Summary Product contains the vertical distribution of the retrieved atmospheric state of ozone (O3), and formal uncertainties measured by the CrIS instruments on the Suomi-NPP satellite through May 21, 2021 and from then on the JPSS-1 (NOAA-20) satellite. The reanalysis stream summary product is global for the time period from 2015-12-01 to 2022-12-31. 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 26 vertical levels from the surface to 0.1 hPa. The principal investigator for the TROPESS project is Kevin W. Bowman.
