TRPSDL2COAIRSFS: Global Carbon Monoxide Vertical Profiles from Aqua Satellite

From February 1, 2021, to the present, this dataset provides daily global vertical profiles of atmospheric carbon monoxide (CO) concentrations. It is derived from measurements by the AIRS instrument on NASA's Aqua satellite, processed using the TROPESS project's MUSES optimal estimation algorithm. The data have a spatial resolution of 13.5 km and are reported at 14 vertical levels from the surface to 0.1 hPa.

Use Cases

• Tracking global pollution transport based on daily, vertically-resolved carbon monoxide concentrations.
• Validating atmospheric chemistry models using satellite-derived CO profiles with formal uncertainties.
• Studying seasonal and interannual variability of a key atmospheric trace gas from 2021 onward.
• Analyzing spatial patterns of combustion-related emissions at a 13.5 km resolution.

Strengths

• Provides a continuous daily record from February 2021 to the present, enabling time-series analysis.
• Offers high vertical resolution with data reported at 14 distinct pressure levels.
• Data is produced by a NASA project (TROPESS) with a named principal investigator, Kevin W. Bowman.

Limitations

• Column names and a precise row count are not provided in the available metadata.
• One source lists a license as 'other-license-specified' while another lists 'None', creating ambiguity about reuse terms.
• The dataset's size is unspecified across all sources.
