Marine Collaborative Ground Segment: Overview of the Ocean Colour Radiometry Platform
Mazeran, Constant; Fanton d'Andon, Odile

MCGS (Marine Collaborative Ground Segment) is a project aimed at making the most of ESA Sentinels satellites' potential for users driven services based on high level products. MCGS addresses the need of the European Space Agency to build up data processing centers in conjunction with the Copernicus Program for the provision of services to local and national, public and private European institutions or entities involved in marine activities. For its innovative content, MCGS has been nominated by the professional clusters "pole Mer PACA", "pole Mer Bretagne" & "Aerospace Valley".

Lead by ACRI-ST and involving 8 French organisations specialised in space oceanography (ACRI-ST, CLS, IFREMER, SHOM, GIS-COOC/LOV, GIS-BRETEL, LEGOS, AS+), MCGS is developping satellite-based services through three dedicated processing centres, complementing the Sentinel "core products", in a collaborative approach with ESA/EUMETSAT: an ocean colour radiometry platform (Sentinel-3 and Sentinel-2), a topography platform (Sentinel-3), and a wind/wave/current platform (Sentinel-1). It will provide environmental information for operational monitoring & support, optimisation of human and material means, respect of regulation at sea and coastal areas.

This presentation will give an overview of the ocean colour radiometry platform, in term of data management, complementary and tailored processing, targeted services and demonstration products.
