Description

The TROPESS AIRS-Aqua 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 AIRS instrument on the EOS Auqa satellite. The reanalysis stream summary product is global for the time period from 2002-09-01 to 2020-03-31. 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 13.5 km (AIRS 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.
