PACE OCI Level-2 Regional Ocean Biogeochemical Properties Data, version 3.1

The Ocean Color Biogeochemical (OC_BGC) suite provides satellite-derived biogeochemical properties of the upper ocean, produced from calibrated, atmospherically corrected ocean-color inputs from PACE_OCI. These products characterize carbon pools and ecosystem status. Geophysical variables in this suite include: - carbon_phyto — Phytoplankton carbon biomass (mg m⁻³) - carbon_phyto_unc — Phytoplankton carbon biomass standard uncertainty (mg m⁻³) - chlor_a — Chlorophyll-a concentration (mg m⁻³) - chlor_a_unc — Chlorophyll-a concentration uncertainty (mg m⁻³) - poc — Particulate Organic Carbon (mg m⁻³) - l2_flags — Level-2 processing flags (bitmask; see per-variable attributes for flag_masks and flag_meanings)
