Methane from Australian wildfire smoke (Suomi-NPP)

TROPESS CrIS-SNPP L2 Methane for Australian Fires, Standard Product V1 (TRPSDL2CH4CRSAUS) at GES DISC
atmosphere NASA GES_DISC Level 2
In plain English

What it measures. How much methane is in the air and how it is layered through the atmosphere, with uncertainty and diagnostic details, focused on the Australia region during the 2019-2020 wildfire outbreak.

How it's made. Derived from the CrIS infrared sounder on the Suomi-NPP satellite, processed by the TROPESS project's optimal-estimation method into daily files for Nov 2019 through Jan 2020.

How & where you'd use it. Helps scientists study how major wildfires release methane and affect the atmosphere during extreme fire events.

Official description

The TROPESS CrIS-SNPP L2 Methane for Australian Fires, Standard Product contains the vertical distribution of the retrieved atmospheric state of methane (CH4), formal uncertainties, and diagnostic information measured by the CrIS instrument on the Suomi-NPP satellite. This product focuses on the Australia region (60S-0S; 100E-177.5E) for the time period from 2019-11-01 to 2020-01-31, during the outbreak of Austrailan 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 26 vertical levels from the surface to 0.1 hPa. The principal investigator for the TROPESS project is Kevin W. Bowman.
