FY3A MERSI Ten-Day Ocean Aerosol Product with 1km Resolution

FY3A MERSI Ten-Day Ocean Aerosol Level 3 Product provides daily aerosol measurements over ocean surfaces. Data is organized into 10x10 degree geographic blocks with a 1km resolution. The product is generated by the SCIOPS organization using the MERSI instrument aboard the FY3A satellite.

Use Cases

• Analyze spatial patterns of aerosol optical thickness across 12 spectral bands (CH6-14,18-20) for climate modeling.
• Calculate the aerosol Angstrom coefficient from multi-band data to infer particle size distribution.
• Correlate aerosol measurements with sun and sensor geometry using sun zenith, sensor zenith, sun azimuth, and sensor azimuth angle fields.
• Study diurnal or seasonal aerosol variability using the data acquisition time stamp for each grid point.

Strengths

• Provides global coverage of ocean aerosol data.
• Offers high spatial resolution of 1 kilometer per grid point.
• Includes multi-spectral aerosol optical thickness data for 12 distinct bands.

Limitations

• Data is limited to ocean surfaces only, with no coverage over land.
• Specific row count, temporal coverage, and update frequency are unknown.
• The raw description mentions 'daily products' but the title specifies 'Ten-Day', creating ambiguity in temporal granularity.
