2 GlobColour: Context and Motivation ESA Earth Observation Envelope ProgrammeESA EOEP-3 Declaration: Specific Objectives...[abridged]…advance the Earth Science agendarespond to the challenges of global change and of anthropogenic effects on our environment,through the development of appropriate new monitoring tools…guarantee easy access to Earth Observation data, including higher level products, for both scienceand application uses;ensure the maximum scientific return on ESA’s investments in Earth Observation;Data User Element (of EOEP)Building user communities through Development and Demonstration of user-driven applicationsof EO dataExploitation of ESA Earth Observation satellites:- ERS 1 & 2- ENVISAT- Earth Explorers: Cryosat-2, SMOS, GOCE, etc.- GMES SentinelsDrawing on research in national and European science programmesSupporting the Earth Science agenda: GlobCarbon, GlobCover, GlobAerosol, GlobIce, GlobVolcano,GlobColour, Medspiration, GlobWave, GlobSnow, etc.Supporting future GMES services- Laying the foundations of a European Service for Global Ocean ColourWorking towards the vision of routine assimilation of all available observations supportingGMES user needs (GlobModel)
3 GlobColour: Context and Motivation Why GlobColour?Ocean colour is an "essential climate variable" needed to support the carboncycle monitoring requirements of the UNFCCC……to understand the role of the biological pump in mitigating CO2 emissions…to understand ocean biology, and what will happen to it under futurechanging conditions of warming, acidification, salinity, circulation, …Encouraging full exploitation of ENVISAT MERIS and GMES Sentinel-3ocean colour instruments.User Consultations with IOCCG, and later IOCCP…led to identification of a strong User Requirement to make combined useof all available global ocean colour observations to provide the best possibleocean colour climate data record to support global change researchNote: IOCCG recommendation on merging in Report #2 (1999).IOCCG Data Merging Working Group meeting (May 2005)Demonstrated the maturity of data merging methods and the feasibility ofachieving the above goal, building on research programs such as SIMBIOS.IOCCG Data Merging Report (IOCCG #5) published 2007.Given that the oceans contain 50 times the carbon contained in the atmosphere, it’s very important to understand what is going to happen to the oceans in a future changing climate.
4 GlobColour: Context and Motivation Specific Objectives of GlobColour:• demonstrate the utility and value of EO-based services to the global ocean colour user community• to provide a long time-series of ocean-colour information for research on the marine component of the global carbon cycle;• to put in place the capacity to continue production of this time series in the future;• to demonstrate the current state of the art in merging together data streams from different satellite based ocean-colour sensors;• to demonstrate a global NRT ocean-colour service based on merged satellite data.Specific User Requirements:Deliver a long time series of consistently calibrated global ocean colour from all available EO sensors:- Chl, TSM, CDOM, water leaving radiances, diffuse attenuation coeff, quality flags, etc., 4km, daily, weekly, monthly, globallyValidate against in-situ and intercompare with other global ocean colour data setsProvide lower spatial/temporal resolution versions of the data set for model assimilationDiagnostic Data Set for validation and further algorithm development
5 GlobColour: Context and Motivation Data User Element Working Process:1. User consultation and formation of a User Group, who provide:User Requirements DocumentLetter of Commitment to actively participate in the project toConfirm and clarify the User Requirements as necessaryProvide technical guidance to the projectParticipate in the validation of the products and serviceTo assess the utility of the products and service2. ESA issues a competitive invitation to tender for the work necessary to satisfy theidentified requirements – open to EOEP programme participants (i.e. ESA member states)3. Projects awarded to European consortia consisting of combination of skills scientific researchers,systems developers, etc.4. Regular user consultation during progress of the projectAttendance at progress meetingsEndorsement of key documentsEvaluationPhased project plan with annual contractual go/no-go milestonesDon’t pay the user
