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 provides a global record of marine remote sensing reflectance. This L4 product integrates data from multiple satellite sensors to provide a consistent and high-quality dataset with a 4 km spatial resolution. The marine reflectance data, which measures the light leaving the ocean surface at various wavelengths, is a fundamental ocean color parameter used to derive other biogeochemical properties like chlorophyll-a concentration and total suspended matter.
