OMPS-NPP: Limb-Profiler Radiance Measurements from Suomi-NPP

Global (-90 to 90 degrees latitude) calibrated radiance measurements from the Ozone Mapping and Profiling Suite (OMPS) Limb-Profiler sensor aboard the Suomi-NPP satellite. The data covers the wavelength region from 280 nm to 1000 nm, with about 14.5 orbits per day, each capturing three limb profiles spaced ~250 km apart from the ground up to ~80 km altitude. Data is stored in HDF5 format, with each granule representing the daylight portion of a full day's orbits.

Use Cases

• Monitoring stratospheric ozone profiles based on limb-viewing ultraviolet and visible radiance measurements.
• Analyzing aerosol vertical distribution using radiance data from the ground up to 80 km altitude.
• Validating atmospheric chemistry models with global, daily orbital data from three cross-track profiles.
• Studying trace gas concentrations from spectral radiances across the 280-1000 nm wavelength range.

Strengths

• Provides global spatial coverage with approximately 14.5 orbits of data per day.
• Offers high vertical resolution for atmospheric profiles, estimated at 1-2 km.
• Cross-platform presence on NASA Earthdata and Data.gov signals its importance and curation.

Limitations

• Column names and specific data structure are not provided in any source description.
• Metadata for size, row count, author, and license is inconsistent or missing across platforms.
• Data is limited to the daylight portion of each orbit.
