OMAERUVG: Daily Global Aerosol Grids from OMI/Aura

0.25x0.25 degree global grids contain daily aerosol data from approximately 15 orbits of the OMI instrument on NASA's Aura satellite. Each file stores all observed pixels within a grid box without averaging, allowing scientists to apply custom filtering schemes. Data is stored in HDF-EOS5 format with a maximum file size of about 50 Mbytes.

Use Cases

• Analyzing daily global aerosol optical depth trends based on near-UV satellite retrievals.
• Studying single scattering albedo for aerosol type classification and climate impact assessment.
• Creating custom gridded climate model inputs by applying specific filters to the raw pixel data.
• Investigating spatial and temporal patterns of atmospheric aerosols from the OMI instrument record.

Strengths

• Provides high-resolution global coverage at a 0.25x0.25 degree grid scale.
• Contains raw pixel-level data within each grid cell, preserving flexibility for user-defined analysis.
• Data is hosted by NASA, indicating authoritative collection and processing standards.

Limitations

• Column names and specific variable counts are not provided in the available metadata.
• Metadata completeness is inconsistent across platforms, with some lacking size, row counts, and license details.
• The 'last updated' date of 2026-04-09 appears to be a future date, indicating potential metadata errors.
