TROPESS CrIS-SNPP: Daily Global Carbon Monoxide Vertical Profiles

NASA's TROPESS project provides daily global vertical profiles of atmospheric carbon monoxide (CO) concentrations from the Suomi-NPP satellite's CrIS instrument. The dataset spans from December 2015 to May 2023, with a spatial resolution of 14 km and reports concentrations across 14 vertical levels from the surface to 0.1 hPa. Data is processed using the MUSES optimal estimation algorithm and is stored in daily netCDF files.

Use Cases

• Analyzing global trends in carbon monoxide pollution based on daily satellite observations.
• Validating atmospheric chemistry models using vertical profile data across 14 pressure levels.
• Studying the spatial distribution of CO emissions with 14 km resolution nadir footprints.
• Investigating long-term changes in atmospheric composition from 2015 to 2023.

Strengths

• Provides vertical distribution across 14 specific levels from surface to 0.1 hPa.
• Offers a long temporal coverage from 2015-12-01 to 2023-05-18.
• Has a defined spatial resolution of 14 km at the CrIS nadir field of view.

Limitations

• Column names and exact variable definitions are not provided in the metadata.
• The dataset's update status and future availability beyond May 2023 are unclear.
• License information is inconsistently reported across platforms.
