OMCLDRR: Cloud Pressure and Fraction from Aura OMI Satellite

OMI/Aura Effective Cloud Pressure and Fraction (Raman Scattering) 1-Orbit L2 Swath 13x24 km V003 (OMCLDRR) is a Level-2 satellite data product providing global measurements of cloud properties. It delivers effective cloud pressure and cloud fraction derived from the Rotational Raman Scattering method, analyzing spectral filling-in between 392 and 398 nm. The dataset includes ancillary parameters, geolocation, viewing angles, and quality flags for each 13x24 km pixel.

Use Cases

• Analyzing global cloud fraction distribution based on the Raman scattering algorithm.
• Studying cloud-top pressure for atmospheric dynamics and climate feedbacks.
• Validating climate models using satellite-derived cloud property data.
• Investigating solar and satellite viewing angle effects on cloud retrievals.
• Assessing data quality for atmospheric composition studies using ancillary flags.

Strengths

• Provides pixel-level data at a spatial resolution of 13x24 km at nadir.
• Based on a specific, peer-reviewed algorithm (Rotational Raman Scattering).
• Contains multiple ancillary parameters, terrain information, and quality flags.
• Data is reprocessed to Version 003, indicating quality control and refinement.

Limitations

• Column names and exact data structure are not specified in the provided metadata.
• Conflicting metadata: one platform lists a last update date of 2026-04-09, which is a future date and may be an error.
• Dataset size and row counts are unknown, limiting immediate assessment of scope.
