Ten-day aggregated satellite data provides aerosol optical thickness over global oceans for four spectral bands and the aerosol Angstrom coefficient. Data is organized into 10x10 degree geographic grid blocks with a 1-kilometer resolution. The product is generated by SCIOPS from the Fengyun-3A (FY3A) satellite's Visible and InfraRed Radiometer (VIRR).
Use Cases
- Analyzing spatial patterns of aerosol optical thickness from the CH9, CH1, CH2, and CH6 spectral bands over ocean surfaces.
- Calculating regional aerosol transport trends using the ten-day aggregated values and the aerosol Angstrom coefficient.
- Validating global climate model aerosol outputs against the 1km-resolution gridded observations.
- Correlating aerosol optical thickness from specific bands with sea surface temperature or wind speed datasets.
Strengths
- Global spatial coverage over all ocean regions.
- Provides four distinct spectral band measurements (CH9, CH1, CH2, CH6) plus the Angstrom coefficient per grid point.
- Data is aggregated into a standardized 10x10 degree geographic grid.
Limitations
- Unknown total row count and dataset size.
- Specific temporal coverage and update recency are not provided.
- Limited to aerosol over ocean; land observations are excluded.
