OMPS-NPP L2 LP: Daily Global Ozone Vertical Profiles

OMPS-NPP L2 LP Ozone (O3) Vertical Profile swath daily 3slit data contains vertical ozone distribution profiles measured by the Ozone Mapping and Profiling Suite Limb-Profiler sensor on the Suomi-NPP satellite. The algorithm derives ozone profile values and errors from the UV and visible spectra, covering altitudes from approximately 12.5 km to 60 km with a vertical resolution of about 1.8 km. Data is provided in HDF5 format from the daylight portions of roughly 14.5 global orbits per day.

Use Cases

• Monitoring stratospheric ozone depletion and recovery based on vertical profile data from 29.5 km to 52.5 km.
• Validating atmospheric chemistry models using global, daily ozone concentration profiles.
• Analyzing seasonal and latitudinal variations in ozone distribution from the ground to ~60 km.
• Studying the impact of cloud presence on lower-altitude ozone retrievals in the visible spectrum.

Strengths

• Provides global spatial coverage from -90 to 90 degrees latitude.
• Offers high vertical resolution for ozone profiles of approximately 1.8 km.
• Data is sourced from a well-established satellite instrument (OMPS LP on Suomi-NPP).

Limitations

• Metadata completeness is inconsistent across platforms, with missing column details, row counts, and size information.
• The dataset's temporal coverage and specific time range are not explicitly stated in the provided sources.
• Relies on daylight portions of orbits, limiting data collection to sunlit regions and times.
