Carbon monoxide over West Coast wildfires (high-res)

TROPESS CrIS-SNPP L2 Carbon Monoxide for West Coast Fires HiRes, Standard Product V1 (TRPSDL2COCRSWCFHI) at GES DISC
atmosphere NASA GES_DISC Level 2
In plain English

What it measures. Measures carbon monoxide and how it stacks up at different altitudes, zoomed in on the continental U.S. during the 2020 West Coast wildfires, with extra detail compared to the standard version.

How it's made. Comes from the CrIS infrared instrument on Suomi-NPP, with the readings turned into actual gas amounts by the MUSES estimation model.

How & where you'd use it. Lets researchers follow how wildfire smoke spread carbon monoxide across the country and how it affected air quality during a major fire season.

Official description

The TROPESS CrIS-SNPP L2 Carbon Monoxide for West Coast Fires HiRes, 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.
