GODAE IGST X, Mercator Status
MERCATOR
Modelling and Assimilation
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 ofnear-real-timealtimeter and insitu data

3. THE CONSORTIUM
( STILL FOLLOWING THE ROADMAP, BUT THINKING ABOUT THE NEW ONE)
GODAE IGST X, Mercator Status
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
Year 2001, Status & CommitmentsIGST 6, 2001
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

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)

SOME ISSUES
GODAE IGST X, Mercator Status
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
