ENVISAT MERIS Level-3 Global Binned Particulate Inorganic Carbon (PIC) Data, version 2022.0
Listed in NASA Earthdata CMR
The Particulate Inorganic Carbon (PIC) data suite includes product of particulate inorganic carbon (calcite, typically from coccolithophores) from ocean-color reflectance using the Balch & Gordon algorithm.
Description
PIC is used to detect and quantify coccolithophore blooms, assess carbonate cycling and optical backscatter, and provide biogeochemical context alongside chlor_a, Kd_490, PAR, and SST. As with all ocean-color retrievals, uncertainties increase in optically complex coastal/inland waters or under high aerosol/glint; users should refer to per-mission algorithm notes and quality flags before analysis.
Geophysical variables in this suite include: - pic — Particulate Inorganic Carbon (Calcite concentration, Balch and Gordon) (mol m⁻³)
