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

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
