Carbon monoxide in the air (wildfire-smoke study, set 1)

TROPESS CrIS-SNPP L2 Carbon Monoxide for Buchholz2021 TS1, Standard Product V1 (TRPSDL2COCRSTS1) at GES DISC
atmosphere NASA GES_DISC Level 2
In plain English

What it measures. Tracks carbon monoxide and how its amount changes at different heights across mid-latitude and tropical regions, for the period late 2015 through early 2019 (a companion set to a related study).

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

How & where you'd use it. Supports pollution and climate research, including international climate assessments, by mapping where carbon monoxide accumulates and travels.

Official description

The TROPESS CrIS-SNPP L2 Carbon Monoxide for Buchholz2021 TS1, Standard Product in support of the IPCC contains 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 mid-latitude and tropical region (between 60S-60N) for the time period from 2015-11-02 to 2019-03-26. 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.
