SWDB_L2: SeaWiFS Aerosol Properties from Deep Blue Algorithm

SeaWiFS Deep Blue (SWDB) Level 2 data provides retrieved aerosol properties from the Sea-viewing Wide Field-of-view Sensor. Each file corresponds to a single satellite swath, with aerosol optical thickness and Angstrom exponent averaged to a 13.5x13.5 km resolution. Approximately 15 of these Level 2 data files are produced per day.

Use Cases

• Tracking aerosol plume movement and density based on aerosol optical thickness measurements.
• Analyzing particle size distribution trends using the Angstrom exponent parameter.
• Validating and improving atmospheric correction models for ocean color remote sensing.
• Studying daily aerosol variability over specific regions from the approximately 15 swaths produced per day.

Strengths

• Provides two key aerosol parameters (aerosol optical thickness and Angstrom exponent) derived from a specific, documented algorithm (Deep Blue).
• Offers a consistent spatial resolution of 13.5x13.5 km at the center of the swath, enabling regional-scale analysis.
• Has a high temporal sampling rate, with approximately 15 data files generated per day.

Limitations

• Critical metadata is missing or conflicting: column names are unknown, and the last updated date conflicts between 2010-12-11 and 2026-04-09.
• The dataset's total size and row count are not provided across any source, hindering an assessment of its full scope.
• Spatial coverage is implied but not explicitly stated, and the specific license terms under 'other-license-specified' are undefined.
