Satellite-derived geophysical variables for aerosol and ocean color studies from the PACE mission's HARP2 instrument. The data is produced by the Fast Multi-Angle Polarimetric Ocean and Land algorithm, which uses a coupled atmosphere-ocean model accelerated by neural networks. The dataset includes aerosol optical thickness, single scattering albedo, layer height, and chlorophyll-a concentration, among other parameters.
Use Cases
- Modeling aerosol radiative forcing based on aerosol optical thickness and single scattering albedo variables.
- Studying phytoplankton dynamics and ocean biogeochemistry based on chlorophyll-a concentration (chla_mapol).
- Analyzing aerosol size distribution and composition based on fine/coarse mode fractions and effective radii.
- Performing multi-angle atmospheric correction for ocean color signals based on angular remote sensing reflectance (Rrs1/Rrs2).
- Investigating aerosol transport and layer properties based on aerosol layer height (alh) and volume density (vd).
Strengths
- Algorithm uses a coupled atmosphere-ocean vector radiative-transfer model, which likely improves physical consistency.
- Retrieval process is accelerated by deep neural networks, suggesting improved computational speed.
- Description lists over 20 specific geophysical variables, including aerosol optical thickness, single scattering albedo, and chlorophyll-a concentration.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
