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). It provides Remote-Sensing Reflectance (Rrs), a fundamental optical property of the water that represents the light leaving the ocean surface. Derived from the Ocean and Land Colour Instrument (OLCI), this L4 dataset is processed into a ready-to-use format. With an exceptionally high spatial resolution of 300 meters, this dataset is particularly valuable for detailed coastal and regional studies of water quality and marine constituents.
