TRPSDL2TATMCRSFS: Vertical Atmospheric Temperature Profiles from Suomi-NPP

TROPESS CrIS-SNPP L2 Atmospheric Temperature provides vertical profiles of atmospheric temperature (TATM) retrieved from the Cross-track Infrared Sounder (CrIS) instrument on the Suomi-NPP satellite. The dataset covers a global period from February 1 to May 21, 2021, with data reported at 31 vertical levels from the surface to 0.1 hPa and a spatial resolution of 14 km. It is processed using the MUSES optimal estimation algorithm and is stored in daily netCDF files.

Use Cases

• Analyzing global vertical temperature distribution based on 31 reported atmospheric levels.
• Assessing satellite retrieval algorithm performance using formal uncertainties and diagnostic information.
• Studying atmospheric state variability during the 2021 observation period.
• Integrating temperature profiles into climate models using geospatial data with 14 km resolution.

Strengths

• Provides high vertical resolution with 31 levels from the surface to 0.1 hPa.
• Offers a defined global time range from 2021-02-01 to 2021-05-21.
• Data is processed using a specific optimal estimation algorithm (MUSES).

Limitations

• Metadata completeness is low; column names, row counts, and file sizes are unknown.
• The dataset's temporal coverage is limited to approximately four months.
• Processing for this specific product was discontinued after May 21, 2021.
