TROPESS CrIS-JPSS1 L2 Methane for Forward Stream, Full Product V2 (TRPSFL2CH4CRS1FS) at GES DISC
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/b7qmnxozcxrb
The TROPESS CrIS-JPSS1 L2 Methane for Forward Stream, Full Product contains the vertical distribution of the retrieved atmospheric state of methane (CH4), formal uncertainties, and diagnostic information measured by the CrIS instrument on the JPSS-1 (NOAA-20) satellite.
Description
The forward stream standard product is global for the time period from 2026-06-01 to present. 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 x 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.
