TRPSDL2PANCRSFS: Global Peroxyacetyl Nitrate Vertical Profiles from Suomi-NPP Satellite

Global satellite data provides the vertical distribution of peroxyacetyl nitrate (PAN) from February 1 to May 21, 2021. The dataset contains retrieved atmospheric states, formal uncertainties, and diagnostic information from the CrIS instrument on the Suomi-NPP satellite, processed using the TROPESS project's MUSES optimal estimation algorithm. Data is reported at 16 vertical levels from the surface to 0.1 hPa with a spatial resolution of 14 kilometers.

Use Cases

• Tracking global PAN transport and its role as a tropospheric ozone precursor based on vertical distribution data.
• Validating chemical transport models using the 16-level vertical profile and formal uncertainty estimates.
• Analyzing short-term atmospheric chemistry trends during the February-May 2021 observation period.
• Studying spatial patterns of atmospheric pollutants at the 14-kilometer nadir field-of-view resolution.

Strengths

• Provides a specific, global 3.5-month time series from February 1 to May 21, 2021.
• Offers detailed vertical resolution with data reported at 16 distinct pressure levels.
• Data is processed using a defined optimal estimation algorithm (MUSES) from the NASA TROPESS project.

Limitations

• Temporal coverage is limited to approximately 3.5 months before processing was discontinued.
• Column names and a precise row/sample count are not provided in the available metadata.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
