NASA's PACE satellite SPEXone instrument provides regional aerosol and ocean color data over ocean regions. The dataset is produced by the OB_CLOUD organization using the Fast Multi-Angle Polarimetric Ocean and Land algorithm (FastMAPOL), which jointly solves for aerosol and ocean parameters. It includes core geophysical variables such as aerosol optical thickness, single scattering albedo, chlorophyll-a concentration, and aerosol layer height.
Use Cases
- Studying aerosol-ocean interactions based on the coupled atmosphere-ocean radiative-transfer model retrievals.
- Analyzing fine and coarse aerosol mode properties based on variables like aot_fine, aot_coarse, ssa_fine, and ssa_coarse.
- Conducting multi-angle atmospheric corrections for ocean color signals based on angular remote sensing reflectance (Rrs1/Rrs2).
- Investigating aerosol composition and size distribution based on variables like effective radius (reff), effective variance (veff), and refractive index (mr/mi).
Strengths
- Algorithm uses a coupled atmosphere and ocean vector radiative-transfer model accelerated by deep neural networks, which the description suggests improves speed and accuracy.
- Provides a simultaneous retrieval of multiple aerosol and ocean parameters, including aerosol optical thickness, single scattering albedo, chlorophyll-a concentration, and aerosol layer height.
Limitations
- Row count, file formats, and column-level documentation are unknown, which may limit suitability assessment.
- Last update date and license information are unknown; freshness and usage rights are unverified.
