OMPS-NPP L1G LP: Satellite Limb Radiance Profiles

OMPS-NPP L1G LP Radiance EV Wavelength-Altitude Grid swath orbital 3slit product contains calibrated earth-viewing radiances from the Ozone Mapping and Profiling Suite Limb-Profiler sensor aboard the Suomi-NPP satellite. It measures radiances across a broad spectrum from 280 nm to 1000 nm, providing vertical profiles from ground level up to about 80 km altitude. The data offers global spatial coverage with approximately 14.5 orbits per day, each capturing three limb profiles spaced roughly 250 km apart.

Use Cases

• Monitoring stratospheric ozone concentration based on ultraviolet radiance measurements.
• Profiling vertical distribution of atmospheric aerosols based on multi-wavelength limb radiance.
• Studiating cross-track atmospheric variability based on three spatially separated limb profiles per orbit.
• Validating atmospheric chemistry models based on global, daily radiance observations.
• Analyzing long-term trends in atmospheric composition based on time-series orbital data.

Strengths

• Provides high vertical resolution profiles of approximately 1-2 km.
• Offers broad spectral coverage from ultraviolet to near-infrared wavelengths (280-1000 nm).
• Delivers global spatial coverage with daily observations from approximately 14.5 orbits.

Limitations

• Column names and specific data structure are not provided in the metadata.
• The exact data volume (size, row count) is unspecified across all sources.
• License details are incomplete, listed only as 'other-license-specified'.
