Objectives
• Satisfy emerging demand for validated merged ocean colour derived information
• Demonstrate the current state of the art in merging together data streams from different ocean-colour sensors:
MERIS, SeaWifs, MODIS-AQUA, POLDER-Parasol
• Provide a long time-series (10 years) of ocean-colour information
• Put in place the capacity to continue production of such time series in the future
• Demonstrate a global NRT ocean-colour service based on merged satellite data
Context ESA DUE project i.e. driven by end users: IOCCG, IOCCP, UK

Validation protocol: to define validation process; based on SIMBIOS validation protocol
Validation of level 2 and level 3 products: • Focus on chlorophyll-a, diffuse attenuation coefficient, normalised
water-leaving radiances (LwN). • Perspectives on CDM and TSM
Validation of the PPS and FPS: daily, weekly, monthly products using:• punctual in situ measurements and (for PPS)• time series obtained from long-term buoy measurements or from
regular/ continuous cruises (e.g. ferrybox datasets) (for PPS)

Inter-comparison with other similar initiatives e.g. NASA REASoN project (preliminary for PPS)
Diagnostic Data Sets: selected from existing validation sites, e.g. IOCCG/SIMBIOS DDS, AMT, ESA MAVT validation sites, Aeronet (for PPS and for characterisation)
Validation (2/2)
First validation effort is done – need to be pursued all along the project
