OMAERUVd: Daily Global Aerosol Optical Depth from OMI/Aura

OMAERUVd is a Level-3 daily global gridded dataset of aerosol properties derived from the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite. It provides extinction and absorption aerosol optical depths at three ultraviolet wavelengths (355 nm, 388 nm, and 500 nm), gridded at a 1.0-degree latitude/longitude resolution. The data is produced by averaging quality-filtered pixel-level measurements from approximately 15 satellite orbits per day.

Use Cases

• Tracking global aerosol transport patterns based on daily gridded optical depth measurements.
• Studying aerosol absorption properties for climate modeling using single scattering albedo data.
• Analyzing long-term trends in atmospheric particulates using the daily time-series data.
• Validating aerosol models with satellite-derived extinction optical depth at three specific wavelengths.

Strengths

• Provides daily, global coverage from a long-running satellite instrument (OMI/Aura).
• Contains specific aerosol optical properties at three ultraviolet wavelengths (355 nm, 388 nm, 500 nm).
• Data is quality-filtered and averaged onto a consistent 1.0-degree global grid.

Limitations

• Key metadata like row count, file size specifics, and exact column names are not provided across sources.
• License information is inconsistently reported ('other-license-specified' vs. 'None').
