OMAERUV: Aura Satellite Aerosol Optical Properties at Three Wavelengths

April 2012 reprocessed data from the Ozone Monitoring Instrument on NASA's Aura satellite provides Level-2 aerosol measurements. Each file contains approximately 53 minutes of data from the sunlit portion of an orbit, with about 14 orbits per day. The product includes aerosol absorption and extinction optical depths, single scattering albedo at 354, 388, and 500 nm wavelengths, and an aerosol index within a 13x24 km field of view.

Use Cases

• Tracking aerosol plume transport based on geolocation parameters and aerosol index.
• Analyzing aerosol absorption properties for climate modeling based on single scattering albedo at three wavelengths.
• Studying regional air quality using aerosol optical depth measurements.
• Validating atmospheric models with satellite-derived aerosol extinction optical depths.

Strengths

• Data is reprocessed using an enhanced algorithm, suggesting improved accuracy.
• Provides measurements at three specific wavelengths (354, 388, and 500 nm) for detailed spectral analysis.
• Has a high spatial resolution with a 13x24 km field of view per observation.

Limitations

• Column names and a precise row count are not provided in the available metadata.
• The dataset's temporal coverage is unclear beyond the April 2012 reprocessing date.
• One platform lists an 'other-license-specified' license while another lists 'None', creating ambiguity.
