Monthly aerosol optical thickness data over global oceans, derived from the FY-3A satellite's MERSI sensor. The product provides measurements for 12 spectral bands, aerosol Angstrom coefficient, and associated geometry angles on a 1km resolution grid organized in 10x10 degree blocks. It is produced by the SCIOPS organization.
Use Cases
- Analyzing seasonal trends in aerosol optical thickness from the 12 spectral bands (CH6-14, 18-20) over specific ocean regions.
- Modeling aerosol particle size distribution by correlating the aerosol Angstrom coefficient with optical thickness across different bands.
- Correcting for solar geometry in reflectance models using the provided sun zenith, sensor zenith, sun azimuth, and sensor azimuth angles.
- Mapping global aerosol transport patterns by aggregating monthly grid data based on the data acquisition time and processing flags.
Strengths
- Global spatial coverage over all ocean areas.
- Provides data for 12 specific spectral bands enhancing spectral analysis.
