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.
Optics multi-sensor, 4km, monthly dataset provides Level 4 Bio-Geo-Chemical
(BGC) data. Derived from multiple satellite observations, this product has a
global spatial resolution of 4 km and a temporal resolution of one month.
