Background
Context
 ESA DUE project i.e. driven by end users: IOCCG, IOCCP, UK Met-Office
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

GlobCOLOUR Project
European Node for global Ocean Colour
The GlobCOLOUR project is demonstrating an EO based service supporting global ocean carbon cycle research. Through this web
portal, the project provides scientists with a long time series of consistently calibrated global ocean colour information.

Validation (1/2)
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)
