SWDB_L3M10: Global Aerosol Optical Properties at 1-Degree Resolution

Global monthly gridded data at a 1.0-degree resolution provides aerosol optical thickness and Angstrom exponent measurements. The dataset is derived from daily SeaWiFS Deep Blue Level 3 satellite observations, offering a long-term aggregated view of atmospheric aerosol properties. It is produced and maintained by the National Aeronautics and Space Administration (NASA).

Use Cases

• Analyzing global aerosol transport patterns based on monthly gridded aerosol optical thickness.
• Studying aerosol particle size variability using the Angstrom exponent parameter.
• Validating and calibrating climate models with satellite-derived aerosol optical properties.
• Investigating seasonal and interannual trends in atmospheric aerosol loading from a long-term satellite record.

Strengths

• Produced by the authoritative source, the National Aeronautics and Space Administration (NASA).
• Provides a consistent, long-term global record derived from the SeaWiFS satellite mission.
• Data is spatially gridded at a uniform 1.0-degree resolution, facilitating global analysis.

Limitations

• Metadata conflicts exist: one platform lists a last update in 2026, while another indicates data from 2010, creating uncertainty about data currency.
• Specific column names, row counts, and file sizes are not provided in the available metadata.
• The license is ambiguously listed as 'other-license-specified' without clear terms for reuse.
