SWDB_L305: Daily Global Aerosol Measurements from SeaWiFS

SeaWiFS Deep Blue Level 3 data provides daily, global gridded measurements of atmospheric aerosols. The primary data parameters are aerosol optical thickness and Angstrom exponent, derived from satellite observations. This dataset is produced by the National Aeronautics and Space Administration and is available on multiple platforms.

Use Cases

• Tracking daily aerosol optical depth over oceans and bright land surfaces based on satellite retrievals.
• Analyzing particle size distribution trends using the Angstrom exponent parameter.
• Studying spatiotemporal patterns of atmospheric aerosols on a 0.5-degree global grid.
• Validating and calibrating aerosol transport models with satellite-derived daily means.

Strengths

• Produced by the National Aeronautics and Space Administration, indicating institutional authority.
• Provides daily temporal resolution for tracking short-term aerosol variability.
• Offers global spatial coverage on a consistent 0.5 x 0.5-degree grid.

Limitations

• Critical metadata conflicts exist: the last update date is reported as both 2010-12-11 and 2026-04-09.
• Specific column names, row counts, and file sizes are not provided in any source description.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
