TROPESS CrIS-SNPP L2 Carbon Monoxide for Australian Fires, Standard Product V1 (TRPSDL2COC

Vertical profiles of atmospheric carbon monoxide (CO) are reported at 14 levels from the surface to 0.1 hPa, derived from the CrIS instrument on the Suomi-NPP satellite. This standard product focuses on the Australia region (60S-0S; 100E-177.5E) for a 3-month period from 2019-11-01 to 2020-01-31, capturing the outbreak of major wildfires. Data are provided in daily netCDF4 files with a spatial resolution of 14 km, generated using the MUSES optimal estimation algorithm by the NASA TROPESS project.

Use Cases

• Tracking wildfire emissions and plume transport based on vertical CO concentration profiles.
• Validating atmospheric chemistry models using satellite-derived CO data with formal uncertainties.
• Studying the temporal evolution of a major pollution event during the specified 3-month time range.
• Analyzing regional air quality impacts from the Australian wildfires using geospatially resolved data.

Strengths

• Provides vertical distribution at 14 specific pressure levels, offering detailed atmospheric structure.
• Covers a defined, critical 3-month event period (2019-11-01 to 2020-01-31) during major wildfires.
• Data has a fine spatial resolution of 14 km at nadir, suitable for regional analysis.
• Product is available on multiple authoritative platforms (Data.gov, NASA Earthdata), indicating vetting and importance.

Limitations

• Column names and a precise row/sample count are not provided in the available metadata.
• Conflicting 'last updated' dates exist between sources (2026-04-09 on Data.gov vs. 2020-01-31 on NASA Earthdata), creating uncertainty about metadata freshness.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
