An algorithm aimed at recovering the radiance scattered and absorbed by the oceanic waters (also called Ocean Colour) from the signal measured by satellite sensors in the visible spectrum. It has been applied to multiple sensors from ESA (MERIS/ENVISAT, MSI/Sentinel-2 and OLCI/Sentinel-3), NASA (SeaWiFS, MODIS/Aqua, VIIRS), and the Korean Geostationary Ocean Colour Imager (GOCI).
used to process for multi-sensor atmospheric correction in the frame of the Ocean Colour Climate change Initiative
used in operational services since 2008
applied to many research projects
One of the strengths of this algorithm is the possibility to recover the Ocean Colour in presence of sun glint. This leads to a much improved spatial coverage compared to previous products.

Observation of the ocean from space by MERIS (Mediterranean Sea, may 1st, 2005). The right part of the image is affected by sun glint, the bright reflection of the sun by the sea surface.
