    • TROPESS CrIS-SNPP L2 Methane for Reanalysis Stream, Summary Product V1 (TRPSYL2CH4CRSRS) at GES DISC

    Metadata Updated: March 12, 2026

    The TROPESS CrIS-SNPP L2 Methane for Reanalysis Stream, Summary Product contains the vertical distribution of the retrieved atmospheric state of methane (CH4), and formal uncertainties measured by the CrIS instrument on the Suomi-NPP satellite. The reanalysis stream summary product is global for the time period from 2015-12-01 to 2021-05-21, when the CrIS-SNPP processing was discontinued for CH4. 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.
