TROPESS CrIS-SNPP: Global Ozone Vertical Profiles from Suomi-NPP Satellite

TROPESS CrIS-SNPP L2 Ozone data provides the vertical distribution of atmospheric ozone (O3) measured by the CrIS instrument on the Suomi-NPP satellite. The forward stream standard product contains retrieved ozone state, formal uncertainties, and diagnostic information at 26 vertical levels from the surface to 0.1 hPa. Data is stored in daily netCDF4 files with a 14 km spatial resolution for a global time period from February to May 2021.

Use Cases

• Analyzing global ozone column variability based on daily vertical profile data.
• Validating atmospheric chemistry models using the 26-level vertical resolution from surface to 0.1 hPa.
• Studying tropospheric ozone precursors using the MUSES optimal estimation algorithm outputs.
• Assessing satellite instrument performance through the included diagnostic information and formal uncertainties.

Strengths

• Provides vertical ozone profiles at 26 specific pressure levels, offering detailed atmospheric structure.
• Data has a defined high spatial resolution of 14 km at the CrIS instrument's nadir field of view.
• Generated using a sophisticated, documented optimal estimation algorithm (MUSES) from the NASA TROPESS project.

Limitations

• Temporal coverage is limited to a short, discontinued period from 2021 02 01 to 2021 05 21.
• Column names and detailed schema are not provided in the available metadata, limiting immediate analysis.
• Key metadata such as row count, file size, and specific license terms are inconsistent or missing across sources.
