TRPSYL2O3CRSRS: Global Ozone Profiles from Suomi-NPP Satellite

TROPESS CrIS-SNPP L2 Ozone for Reanalysis Stream provides the vertical distribution of atmospheric ozone (O3) and its uncertainties, retrieved from the Cross-track Infrared Sounder (CrIS) on the Suomi-NPP satellite. The dataset uses the MUSES optimal estimation algorithm to produce daily global files from December 2015 to May 2023. Data are reported at 26 vertical levels from the surface to 0.1 hPa with a spatial resolution of 14 km at nadir.

Use Cases

• Monitoring long-term ozone layer trends based on the 2015-2023 global time series.
• Validating atmospheric chemistry models using the 26-level vertical ozone profiles.
• Assessing regional air quality and pollution transport using the 14 km spatial resolution data.
• Conducting reanalysis studies for climate science using the MUSES algorithm-retrieved ozone state.

Strengths

• Provides a long-term, consistent global record from December 2015 to May 2023.
• Offers high vertical resolution with profiles reported at 26 distinct pressure levels.
• Utilizes a sophisticated, peer-reviewed retrieval algorithm (MUSES) that incorporates multiple spectral signatures.

Limitations

• Dataset metadata is incomplete; column names and exact row/file counts are not provided in the sources.
• The data stream ended in May 2023, limiting analysis of more recent atmospheric conditions.
• License is ambiguously specified as 'other-license-specified', requiring further investigation for use.
