NASA TROPESS: Global Satellite Ozone and Ammonia Profiles from 2021

The NASA TROPESS project provides vertical profiles of atmospheric ozone and ammonia measured by the AIRS and OMI satellite instruments. Data is global, spans from February 1, 2021 to the present, and is reported at 26 vertical levels for ozone and 15 for ammonia. The principal investigator is Kevin W. Bowman.

Use Cases

• Monitoring global tropospheric ozone pollution trends based on the vertical distribution data.
• Analyzing atmospheric ammonia sources and transport based on the retrieved vertical state.
• Validating and improving chemical transport models using the satellite-derived profiles and formal uncertainties.
• Studying the spatial and temporal variability of key atmospheric precursors mentioned in the description.

Strengths

• Data has a defined global spatial coverage and a continuous temporal range from 2021-02-01 onward.
• Vertical profiles are reported at a high resolution of 26 levels for ozone and 15 levels for ammonia.
• Includes formal uncertainties and diagnostic information for the retrieved atmospheric state.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download from the netCDF files.
• Row count is unknown, which may limit suitability assessment for specific ML tasks.
