Carbon monoxide in the air (wildfire-smoke study)

TROPESS CrIS-SNPP L2 Carbon Monoxide for Buchholz2021 TS2, Standard Product V1 (TRPSDL2COCRSTS2) at GES DISC
atmosphere NASA GES_DISC Level 2
In plain English

What it measures. Captures carbon monoxide, a gas produced by burning, and shows how its amount varies at different heights in the air across mid-latitude and tropical regions from late 2015 through early 2019.

How it's made. Derived from infrared light recorded by the CrIS instrument on Suomi-NPP, processed through the MUSES model that estimates the real gas amounts.

How & where you'd use it. Supports studies of air pollution and climate, including work tied to international climate assessments, by showing where carbon monoxide builds up and travels.

Official description

The TROPESS CrIS-SNPP L2 Carbon Monoxide for Buchholz2021 TS2, 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.
