Monthly global aerosol data over oceans from the FY-3A satellite's Visible and Infrared Radiometer (VIRR). The product provides aerosol optical thickness for four spectral bands and the Angstrom coefficient, gridded in 10x10 degree geographic blocks with 1-kilometer resolution. The data is produced by the organization SCIOPS.
Use Cases
- Modeling aerosol radiative forcing over oceans using aerosol optical thickness from bands CH9, CH1, CH2, and CH6.
- Analyzing seasonal aerosol particle size distributions via the aerosol Angstrom coefficient column.
- Mapping global monthly aerosol transport patterns using the 1km resolution geospatial longitude/latitude grid.
- Correlating ocean aerosol levels with other climate variables using the 10x10 degree geographic block structure.
Strengths
- Global spatial coverage over all ocean regions.
- 1-kilometer spatial resolution for detailed analysis.
- Includes aerosol properties for four distinct spectral bands (CH9, CH1, CH2, CH6).
Limitations
- Data is limited to aerosol over ocean surfaces, excluding land areas.
- Specific row count, temporal range, and update recency are unknown.
- Data quality and completeness depend on satellite sensor performance and atmospheric correction algorithms.
