TROPESS CrIS-JPSS1: Global Carbon Monoxide Vertical Profiles

Fourteen vertical levels from the surface to 0.1 hPa provide a detailed view of atmospheric carbon monoxide distribution. This dataset contains daily global maps of carbon monoxide concentrations and uncertainties, retrieved from the CrIS instrument on the NOAA-20 satellite using the MUSES optimal estimation algorithm. Data is stored in netCDF4 files with a spatial resolution of 14 kilometers at nadir.

Use Cases

• Tracking long-range transport of pollution based on daily global CO concentration maps.
• Validating atmospheric chemistry models using vertical profile data across 14 pressure levels.
• Analyzing seasonal and interannual trends in carbon monoxide based on a continuous record from 2021 to present.
• Studying source-sink relationships of CO using spatially resolved data with formal uncertainty estimates.

Strengths

• Provides vertical distribution across 14 levels from the surface to 0.1 hPa, offering detailed atmospheric structure.
• Has a continuous global time series from April 1, 2021, to the present.
• Includes formal uncertainty estimates for each retrieved carbon monoxide value.
• Features a high spatial resolution of 14 kilometers at the satellite's nadir field of view.

Limitations

• Metadata completeness is low; column names and exact row/size counts are not provided in the sources.
• License information is ambiguous, listed only as 'other-license-specified' without details.
• The last update date (2026-04-09) appears to be a future date, which may indicate a metadata error.
