Satellite-derived aerosol and ocean color properties over global oceans, produced by the FastMAPOL algorithm. The dataset includes aerosol optical thickness, single scattering albedo, and chlorophyll-a concentration among other variables. The data originates from NASA's PACE mission and is provided by OB_CLOUD.
Use Cases
- Analyze aerosol fine mode fraction (fmf) and effective radius (reff_fine) to classify marine aerosol types.
- Correlate chlorophyll-a concentration (chla_mapol) with aerosol optical thickness (aot) to study phytoplankton-aerosol links.
- Validate aerosol layer height (alh) retrievals against other satellite or lidar datasets.
- Study spectral dependence of aerosols using the Ångström exponent (angstrom) for 440–670 nm and 440–870 nm.
- Investigate ocean surface conditions by combining wind_speed data with aerosol volume density (vd).
Strengths
- Simultaneous retrieval of over 20 core geophysical variables for aerosol and ocean properties.
- Algorithm uses a coupled atmosphere-ocean radiative transfer model accelerated by deep neural networks for improved accuracy.
Limitations
- Dataset size, row count, and specific temporal coverage are unknown, limiting assessment of statistical significance.
- Data is limited to ocean surfaces, excluding aerosol properties over land.
