PACE OCI Level-3 Global Mapped Closed-Loop Ocean Simulation for Evaluation Data, version 3.1

Products include hyperspectral remote sensing reflectance, chlorophyll-a concentration, diffuse attenuation coefficients, aerosol optical properties, and derived absorption and backscattering properties. The mapped format supports visualization, regional and global analysis, comparison with modeled input properties, and assessment of retrieval performance and uncertainty.

Geophysical variables in this suite include: - Rrs — Remote sensing reflectance (sr⁻¹) - chlor_a — Chlorophyll-a concentration from the OCI algorithm (mg m⁻³) - Kd — Diffuse attenuation coefficients from the Lee algorithm (m⁻¹) - a — Total absorption from the GIOP model (m⁻¹) - adg — Absorption due to colored dissolved and detrital material from the GIOP model (m⁻¹) - aph — Phytoplankton absorption from the GIOP model (m⁻¹) - bb — Total backscattering from the GIOP model (m⁻¹) - bbp — Particulate backscattering from the GIOP model (m⁻¹) - angstrom — Aerosol Ångström exponent from 443 to 865 nm - aot_865 — Aerosol optical thickness at 865 nm
