PACE SPEXone Level-3 Global Mapped Ocean Properties, RemoTAP Algorithm Data, version 4.0

The suite includes spectral aerosol optical depth (AOD), single-scattering albedo (SSA), complex refractive index (real/imaginary), size distribution metrics (e.g., fine/coarse effective radii and fine-mode fraction), and aerosol shape/fraction spherical; it also reports ocean surface roughness (glint/wind parameterization) and “ocean body” properties that define the water-leaving signal for consistency with the coupled atmosphere–ocean inversion.

Use AER_RTAPOCEAN for aerosol-climate and air-quality studies, as aerosol context for ocean-color atmospheric correction, and for model evaluation and data assimilation; pair it with OCI/HARP2 products for cross-sensor analyses. Core geophysical variables in this suite include: - chlor_a – Chlorophyll concentration (mg m⁻³) The RemoTAP Level-3 Chlorophyll-a (Chla) product provides estimates of surface chlorophyll-a concentration, a commonly used proxy for phytoplankton biomass.
