GlobColour: Context and Motivation • ESA Earth Observation Envelope Programme • ESA EOEP-3 Declaration: Specific Objectives...[abridged]… • advance the Earth Science agenda • respond 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 science • and 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 applications • of EO data • Exploitation of ESA Earth Observation satellites: • - ERS 1 & 2 • - ENVISAT • - Earth Explorers: Cryosat-2, SMOS, GOCE, etc. • - GMES Sentinels • Drawing on research in national and European science programmes • Supporting 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 Colour • Working towards the vision of routine assimilation of all available observations supporting • GMES user needs (GlobModel)
GlobColour: Context and Motivation • Why GlobColour? • Ocean colour is an "essential climate variable" needed to support the carbon • cycle 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 future • changing conditions of warming, acidification, salinity, circulation, … • Encouraging full exploitation of ENVISAT MERIS and GMES Sentinel-3 • ocean colour instruments. • User Consultations with IOCCG, and later IOCCP • …led to identification of a strong User Requirement to make combined use • of all available global ocean colour observations to provide the best possible • ocean colour climate data record to support global change research • Note: 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 of • achieving the above goal, building on research programs such as SIMBIOS. • IOCCG Data Merging Report (IOCCG #5) published 2007.
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. • - 1997-2007, 4km, daily, weekly, monthly, globally • Validate against in-situ and intercompare with other global ocean colour data sets • Provide lower spatial/temporal resolution versions of the data set for model assimilation • Diagnostic Data Set for validation and further algorithm development
GlobColour: Context and Motivation • Data User Element Working Process: • 1. User consultation and formation of a User Group, who provide: • User Requirements Document • Letter of Commitment to actively participate in the project to • Confirm and clarify the User Requirements as necessary • Provide technical guidance to the project • Participate in the validation of the products and service • To assess the utility of the products and service • 2. ESA issues a competitive invitation to tender for the work necessary to satisfy the • identified 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 project • Attendance at progress meetings • Endorsement of key documents • Evaluation • Phased project plan with annual contractual go/no-go milestones
GlobColour: Context and Motivation • The GlobColour Project: • ESA project: • Budget = k€ 975 • Kick-Off = 15 Nov 2005 • Year 1 2006 – Development, prototyping and testing • Year 2 2007 – Production of data set and validation against in-situ • Year 3 2008 – One-year demonstration NRT service • Consortium: • ACRI-ST (F) • LOV (F) • University of Plymouth (UK) • ARGANS Ltd (UK) • Brockmann Consult (D) • NIVA (N) • ICESS (USA) • DLR (D) • User Group: • IOCCG - Ocean Colour Science Requirements • IOCCP - Ocean Carbon Science Requirements • UKMO-NCOF - Operational Application Requirements
