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

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

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

17. 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 n January : –First Mercator prototype approval. First bulletin 17 january 2001. Commitments for Routine demonstration phase (2001->Godae) n 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 Year 2001, Status & Commitments IGST 6, 2001

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

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

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

24. SOME ISSUES GODAE IGST X, Mercator Status

25. n The High Resolution Global Ocean –A European responsability, a GODAE challenge –MERSEA project n The link global / regional / coastal –MERSEA then other national/EC proposals n 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 n Reinforce validation methodology of the system –Scores and metrics, system intercomparisons, data sharing, … n Improve the system again and again (model, assimilation, data, …) –National initiatives –MERSEA, GODAE
