Carbon monoxide from West Coast wildfire smoke (Suomi-NPP)

TROPESS CrIS-SNPP L2 Carbon Monoxide for West Coast Fires, Standard Product V1 (TRPSDL2COCRSWCF) at GES DISC
atmosphere NASA GES_DISC Level 2
In plain English

What it measures. Shows how much carbon monoxide was in the air at different heights over the U.S. during a specific window in 2020, with uncertainty estimates. Carbon monoxide is a clear fingerprint of wildfire smoke.

How it's made. Derived from the CrIS instrument on the Suomi-NPP satellite using the TROPESS estimation method, focused on the continental U.S. during the August-to-October 2020 West Coast fires.

How & where you'd use it. Built to study the smoke from that major wildfire outbreak, tracking how much carbon monoxide the fires released and where the plumes traveled.

Official description

The TROPESS CrIS-SNPP L2 Carbon Monoxide for West Coast Fires, Standard Product contains the vertical distribution of the retrieved atmospheric state of carbon monoxide (CO), formal uncertainties, and diagnostic information measured by the CrIS instrument on the Suomi-NPP satellite. This product focuses on the CONUS region (20N-60N; 150W-40W) for the time period from 2020-08-01 to 2020-10-31, during the outbreak of U.S. West Coast wildfires. 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 14 vertical levels from the surface to 0.1 hPa. The principal investigator for the TROPESS project is Kevin W. Bowman.
