TROPESS AIRS-Aqua and OMI-Aura L2 Ozone for Forward Stream, Standard Product V2 (TRPSDL2O3AIRSOMIFS) at GES DISC
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/ag43d8jz0cog
Description
The TROPESS AIRS-Aqua and OMI-Aura L2 Ozone for Forward Stream, Standard Product contains the vertical distribution of the retrieved atmospheric state of ozone (O3), formal uncertainties, and diagnostic information measured by the AIRS instrument on the EOS Aqua satellite and the OMI instrument on the EOS Aura satellite. The forward stream standard product is global for the time period from 2021-02-01 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 13 km x 24 km (OMI 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.
