OMPS-NPP Satellite Ozone Vertical Profiles in Near Real Time

OMPS-NPP L2 NP Ozone (O3) Vertical Profile data provides ozone retrievals from the Suomi-NPP satellite's Nadir-Profiler instrument. The dataset contains ozone mixing ratios at 15 pressure levels, total ozone columns, UV aerosol index, and reflectivities, with global coverage from -82 to +82 degrees latitude. Data is produced in Near Real Time by the OMINRT organization and is stored in HDF5 format.

Use Cases

• Analyzing vertical ozone distribution across 15 pressure levels from 50 to 0.5 hPa.
• Tracking global total ozone column changes for monitoring the ozone layer.
• Investigating aerosol presence in the stratosphere using the UV aerosol index.
• Studiating surface reflectivity properties from satellite measurements at 331 and 380 nm.
• Mapping near-real-time ozone profiles along Suomi-NPP satellite orbital swaths.

Strengths

• Provides vertical profile data at 15 specific pressure levels, offering detailed atmospheric structure.
• Delivers near-global spatial coverage (-82 to +82 degrees latitude) with approximately 14.5 orbits per day.
• Includes multiple derived products: ozone profiles, total column, aerosol index, and reflectivities in a single granule.
• Uses the V8 algorithm combining measurements from two spectral ranges (250-310 nm and 300-380 nm) for retrieval.

Limitations

• Column names and specific data schema are not provided by any source, complicating direct analysis.
• Sources conflict on license information, with one specifying 'other-license-specified' and another listing 'None'.
• The spatial coverage is limited to latitudes between -82 and +82 degrees, excluding polar regions.
