Description

The Global Ocean Colour (Copernicus-GlobColour) dataset is a Bio-Geo-Chemical (BGC) product developed by ACRI-ST. Derived from multiple satellite sources like SeaWiFS, MODIS, and OLCI. It provides a comprehensive range of oceanographic variables, including: Chlorophyll (CHL), Phytoplankton Functional types and sizes (PFT), Primary Production (PP), Suspended Matter (SPM), Secchi Transparency Depth (ZSD), Diffuse Attenuation (KD490), Particulate Backscattering (BBP), Absorption Coefficient (CDM), Reflectance (RRS) and more.

This dataset is a global product from the Copernicus Marine Service (CMEMS) focused on ocean plankton. This dataset is derived specifically from the Ocean and Land Colour Instrument (OLCI) on the Sentinel-3 satellites and provides a very high spatial resolution of 300 meters, making it ideal for coastal and regional-scale analysis.The primary layer is chlorophyll-a concentration (CHL), which serves as a proxy for the biomass of phytoplankton, a crucial component of the marine food web.
