TROPESS CrIS-SNPP: Global Carbon Monoxide Vertical Profiles

TROPESS CrIS-SNPP L2 Carbon Monoxide for Forward Stream, Standard Product provides the vertical distribution of atmospheric carbon monoxide (CO) measured by the CrIS instrument on the Suomi-NPP satellite. The dataset includes retrieved CO concentrations, formal uncertainties, and diagnostic information, processed using the MUSES optimal estimation algorithm. It offers global coverage at a 14 km spatial resolution across 14 vertical levels from the surface to 0.1 hPa.

Use Cases

• Analyzing global carbon monoxide pollution sources and transport based on vertical concentration profiles.
• Validating atmospheric chemistry and transport models using satellite-derived CO measurements with formal uncertainties.
• Studying temporal changes in atmospheric CO concentrations during the 2021 observation period.
• Assessing satellite instrument performance and retrieval algorithm diagnostics from the MUSES processing system.

Strengths

• Provides vertical profiles at 14 discrete levels from the surface to 0.1 hPa, offering detailed atmospheric structure.
• Has a defined spatial resolution of 14 km at the CrIS nadir field of view.
• Includes formal uncertainties and diagnostic information alongside the retrieved state.

Limitations

• Time coverage is limited to a specific period from 2021-02-01 to 2021-05-21, after which processing was discontinued.
• Column names and specific variable details are not provided in the available metadata.
• Exact dataset size (file count, total rows) is unknown across all sources.
