PACE SPEXone Level-3 Global Mapped Ocean Properties, RemoTAP Algorithm Data, version 3.0

This suite provides aerosol optical/microphysical properties retrieved over the oceans, along with coupled surface parameters used in the retrieval. 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:
The RemoTAP Level-3 Chlorophyll-a (Chla) product provides estimates of surface chlorophyll-a concentration, a commonly used proxy for phytoplankton biomass. Values are derived using the RemoTAP algorithm.

In the current version, the variable is named chlor_a, with the long name “Chlorophyll-a concentration, OCI algorithm.” The variable and its long name will be updated in a future release to correctly reference the RemoTAP algorithm.

Geophysical variable included:
- chlor_a – Chlorophyll concentration (mg m⁻³)
