Description
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. 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)

Variables
The table below lists the variables contained within a single granule for this dataset. Variables often contain observed or derived geophysical measurements collected from a variety of sources, including remote sensing instruments on satellite and airborne platforms, field campaigns, in situ measurements, and model outputs. The terms variable, parameter, scientific data set, layer, and band have been used across NASA’s Earth science disciplines; however, variable is the designated nomenclature in NASA’s Common Metadata Repository (CMR). Variable metadata attributes such as Name, Description, Units, Data Type, Fill Value, Valid Range, and Scale Factor allow users to efficiently process and analyze the data. The full range of attributes may not be applicable to all variables. Additional information on variable attributes is typically available in the data, user guide, and/or other product documentation.
