OMPS-NPP: Stratospheric Temperature Profiles from Limb Sounding

OMPS-NPP LP L2 Temperature Vertical Profile swath daily 3-slit V1.0 contains daily global temperature profiles from the ground up to about 60 km, measured by the Ozone Mapping and Profiling Suite Limb-Profiler sensor on the Suomi-NPP satellite. The data provides a vertical resolution of approximately 1.8 km and is derived from the center slit of the instrument's three-slit design during the daylight portion of about 14.5 orbits per day. It is stored in Hierarchical Data Format Version 5 (HDF5) and is produced by the National Aeronautics and Space Administration.

Use Cases

• Monitoring stratospheric temperature trends based on daily global vertical profiles.
• Validating atmospheric models using temperature data with approximately 1.8 km vertical resolution.
• Studying polar vortex dynamics using global latitude coverage from -90 to 90 degrees.
• Analyzing diurnal and seasonal atmospheric variability from the approximately 14.5 daily orbital swaths.

Strengths

• Provides global spatial coverage from -90 to 90 degrees latitude.
• Offers high vertical resolution of approximately 1.8 km for atmospheric profiles.
• Data is produced by the authoritative source, the National Aeronautics and Space Administration.

Limitations

• Metadata completeness is low, with column names, row counts, and file sizes unknown across all sources.
• Conflicting license information exists between platforms ('other-license-specified' and 'None').
• Documentation gaps are present, as specific data variables and quality flags are not described.
