Ozone in the air over Australian wildfires

TROPESS CrIS-SNPP L2 Ozone for Australian Fires, Standard Product V1 (TRPSDL2O3CRSAUS) at GES DISC
atmosphere NASA GES_DISC Level 2
In plain English

What it measures. How ozone is distributed at different heights in the air over Australia during the major 2019-2020 wildfire season, along with uncertainty and quality information.

How it's made. Retrieved from the CrIS infrared sounder on the Suomi NPP satellite using the TROPESS project's optimal-estimation algorithm, with one file per day at about 14 km resolution.

How & where you'd use it. Lets researchers study how the intense Australian bushfires affected ozone in the atmosphere over that region and time.

Official description

The TROPESS CrIS-SNPP L2 Ozone for Australian Fires, Standard Product contains the vertical distribution of the retrieved atmospheric state of ozone (O3), 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.
