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)

See S. Lavender, D. Antoine, S.Maritorena ’s presentation

Validation (1/2)



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
