MAPOL_OCEAN provides simultaneous aerosol and ocean color products using the Fast Multi-Angle Polarimetric Ocean and Land algorithm. The dataset includes core geophysical variables such as aerosol optical thickness, chlorophyll-a concentration, and aerosol layer height. It is produced by OB_CLOUD from NASA Earthdata using the SPEXone instrument on the PACE satellite.
Use Cases
- Analyze aerosol fine mode fraction (fmf) and Ångström exponent (angstrom) to classify aerosol types and sources over global oceans.
- Model phytoplankton dynamics by correlating chlorophyll-a concentration (chla_mapol) with aerosol optical thickness (aot) and ocean surface wind speed (wind_speed).
- Validate aerosol microphysical models using columns for effective radius (reff_fine/coarse), volume density (vd), and refractive index (mr/mi).
- Assess radiative forcing by combining aerosol single scattering albedo (ssa) and aerosol layer height (alh) data in atmospheric simulations.
- Perform multi-angle atmospheric correction for ocean color by using angular remote sensing reflectance (Rrs1/Rrs2) before and after BRDF correction.
Strengths
- Simultaneous retrieval of over 20 aerosol and ocean parameters from a single sensor.
- Algorithm uses a coupled atmosphere-ocean vector radiative-transfer model accelerated by deep neural networks for improved accuracy.
Limitations
- Specific row count, geographic granularity, and temporal coverage are not provided in the input.
- Data quality is contingent on the performance of the FastMAPOL algorithm and SPEXone sensor calibration.
