OMPS-NPP: Ozone Vertical Profiles from Suomi-NPP Satellite

Orbital data from the Suomi-NPP satellite's OMPS Nadir-Profiler instrument provides daily global ozone profiles. The V8 algorithm reports ozone mixing ratios at 15 pressure levels between 50 and 0.5 hPa, along with total ozone column, UV aerosol index, and reflectivity measurements. Each daily granule contains data from approximately 14.5 orbits, with a spatial coverage from -82 to +82 degrees latitude and a footprint size of 250 km x 250 km.

Use Cases

• Monitoring stratospheric ozone layer health based on vertical profile data at 15 pressure levels.
• Analyzing spatial and temporal trends in total ozone column across global daylight regions.
• Investigating aerosol-ozone interactions using the included UV aerosol index measurement.
• Validating atmospheric chemistry models with satellite-derived ozone mixing ratio profiles.

Strengths

• Provides vertical ozone profiles at 15 specific pressure levels between 50 and 0.5 hPa.
• Offers daily global spatial coverage from -82 to +82 degrees latitude.
• Contains multiple derived measurements including total ozone, UV aerosol index, and reflectivities.

Limitations

• Key metadata such as row count, column names, and exact temporal coverage are unavailable across all sources.
• Data is limited to the daylight portion of orbits, excluding nighttime measurements.
• The 'other-license-specified' license tag lacks clear, accessible terms.
