  3. MERCATORModelling and Assimilation IGST 6, 2001 • In 2003, the modeling/assimilation unit of the MERCATOR system will be based on two components : Assimilation of near-real-time altimeter and in situ data Common boundary : 9° N Atlantic • an intermediate resolution (1/4°) Global Ocean model • a high resolution (1/15°) North Atlantic model, including the Mediterranean sea Bahurel IGST VI, Gulfport, 4-7 December 2001

  4. #1 1/3° 1/15° #2 2° 1/15° #3 1/4° Mercator roadmap towards GODAE (Incremental Development) Oct 2005 ¼° Global  Global Target system: Global Ocean and High Resolution Jan 2003 1/15° N.Atlantic & Med Sea  High Res. Jan 2001 1/3° N.Atlantic  Real time Strategy: From REGIONAL to GLOBAL From R&D to OPERATIONAL From Altimetry to MultiData

  14. ( AROUND 300 USERS, AN INCREASING NUMBER) 2. SOME USERS GODAE IGST X, Mercator Status

  15. Users of Mercator numerical products (Mercator members removed)

  16. ( STILL FOLLOWING THE ROADMAP, BUT THINKING ABOUT THE NEW ONE) 3. THE CONSORTIUM GODAE IGST X, Mercator Status

  17. Year 2001, Status & Commitments IGST 6, 2001 2001, Status • Project Team (around 25 people) • A Science Working Team, around 20 research teams (~70 people) • Links with european FOAM (UK), DIADEM (Norway) and MFSPP (Italy) forecastings projects ; US Atlantic project (GODAE). 2001, Commitments • January : • First Mercator prototype approval. First bulletin 17 january 2001. Commitments for Routine demonstration phase (2001->Godae) • September : • Mercator Implementation and Budget Plan Approval for years 2002-2005 (GODAE demonstration phase) • Commitments for the creation in early 2002 of an independent joint agency called MERCATOR OCEAN • Plans for an operational center in 2006

  18. Focus : Operational Center • Executive officers of Mercator « patrons » agencies (CNES, CNRS, IFREMER, IRD, Météo-France, SHOM) changed a lot, but … • Commitments for a Mercator operational center still OK • Schedule : Target is april 2006 • Mission: continuity, but evolution towards • Services (after R&D demo) • European integration • Sustained activity • Partnership • CLS should be associated closely as a member • Partnership is open and welcomed European GMES « core Service »

  19. Building the GMES Marine Core Service GMES Core information (ocean state) GMES input information (raw data) User tailored information (user products) Satellite and in situ networks Marine Core Service Marine Downstream Services End-Users GMES Service outputs (others)

  20. ( MERSEA Integrated SYSTEM V1 AVAILABLE) ( MERSEA Target Operational Period, ONGOING) ( MERCATOR IN MERSEA IS GLOBAL & METRICS) 4. MERSEA GODAE IGST X, Mercator Status

  22. Mercator/Mersea Roadmap to High Resolution Global Ocean • Demonstrator : GLOBAL ¼° + N.ATL / MED 1/12° • Version 1, achieved • Version 2 : advanced modelling, multivariate and regulard grid • Target : GLOBAL 1/12° • Version 0 by 2008 1 Global ¼° 2 Global 1/12°

  23. Metrics • (WP5 in MERSEA project) • The « metrics » activity integrated in the VALIDATION activity in Mercator • F.Hernandez • L.Crosnier • N.Verbrugge • …. • with contribution from the whole project team (e.g. G.Garric on ice metrics) • GODAE impetus is fundamental to MERSEA

  24. SOME ISSUES GODAE IGST X, Mercator Status

  25. The High Resolution Global Ocean • A European responsability, a GODAE challenge • MERSEA project • The link global / regional / coastal • MERSEA then other national/EC proposals • Define, promote and develop with European partners the Ocean Forecasting « core service » • Condition for sustainability; consolidation after demonstration • MERSEA project ; GMES program • Data continuity issue • Reinforce validation methodology of the system • Scores and metrics, system intercomparisons, data sharing, … • Improve the system again and again (model, assimilation, data, …) • National initiatives • MERSEA, GODAE
