TROPESS CrIS-SNPP L2 CO: Vertical Profiles from Suomi-NPP Satellite

14 vertical levels from the surface to 0.1 hPa provide the retrieved atmospheric state of carbon monoxide (CO) measured by the CrIS instrument on the Suomi-NPP satellite. The TROPESS project's MUSES algorithm generates this standard product for the IPCC, covering mid-latitude and tropical regions between 60S-60N. Each daily netCDF file contains CO distribution, formal uncertainties, and diagnostic information from November 2015 to March 2019.

Use Cases

• Analyzing vertical distribution of carbon monoxide based on the 14 reported vertical levels.
• Assessing formal uncertainties in satellite retrievals for model validation.
• Studying mid-latitude and tropical CO trends from 2015-2019 for climate research.
• Using diagnostic information to evaluate the performance of the MUSES optimal estimation algorithm.
• Mapping daily CO concentrations at a 14 km spatial resolution for regional air quality studies.

Strengths

• Provides vertical profiles at 14 specific levels from surface to 0.1 hPa.
• Uses a defined optimal estimation algorithm (MUSES) for retrieval.
• Has a consistent daily temporal resolution and 14 km spatial resolution.
• Covers a multi-year time range from 2015-11-02 to 2019-03-26.

Limitations

• Column names and exact dataset size (rows, file size) are unknown across all sources.
• Metadata freshness is conflicting: one source lists an update in 2026, another in 2019.
• Spatial coverage is limited to the region between 60S and 60N, excluding polar areas.
