3. The 9th Science Team Meeting of GHRSST-PP Perros-Guirec June 2008 Monitoring the ocean : the MERCATOR system Observations From space Observations In situ model Forecasts

4. The 9th Science Team Meeting of GHRSST-PP Perros-Guirec June 2008 SST a unique field for describing the air-sea interface : air-sea exchanges, atmospheric boundary condition, ocean assimilation and valdation

5. The 9th Science Team Meeting of GHRSST-PP Perros-Guirec June 2008 Météo-France : a supporter of upper ocean research and monitoring  Member of the GIP Mercator Ocean : –contribution in terms of financing, human resources and computer resources  Contribution to FP6 EU-project Mersea, FP7 EU-project MyOcean  Research Centre (CNRM) –Air-sea fluxes measurements and parameterization (ECUME) –Coupled modelling and forecast –In situ surface buoys and coordination of the european monitoring network (Esurfmar)  Marine Division (DPREVI/MAR) –Institutional responsabilities for marine security and crisis management at the national level (ex : POLMAR) and the international level (ex : GMDSS, MPERSS)  Space division (CMS) –Operational responsability of the SAF OSI (ocean and sea ice) from EUMETSAT

6. The 9th Science Team Meeting of GHRSST-PP Perros-Guirec June 2008 Contribution to GMES/MyOcean 81 man.month on 3 years  System engineering and quality control (WP 2)  Contribution to the « Thematic Assembly Centre » for SST satellite products (TAC SST, WP 13)  Integration and evaluation of SST global products in national and international downstream services (WP19.1) Objectif of the TAC SST (leader : UK Met Office) : operational furniture to the ocean forecast centres and downstream users of satellite SST products from one- or multi-captors, with the required validation and quality control, downstream from the ground segment of the different satellites (EUMETSAT, ESA, NOAA…) Contribution to the TAC SST assured by the CMS/Météo France : –Operational coordination of the TAC SST –Operational furniture of satellite SST products from multi-captors, at very high resolution over european seas –Quality control in real time of the different sources of satellite SST and elaborated products

7. The 9th Science Team Meeting of GHRSST-PP Perros-Guirec June 2008 Example of multi-captor SST satellite product (MERSEA)

8. The 9th Science Team Meeting of GHRSST-PP Perros-Guirec June 2008 Contribution to downstream services  Short and medium range meteorological forecast : use of analysed and forecasted SST in order to improve the quality of forecast for potentially dangerous or damaging phenomena (ex: tropical cyclons, « cevenol » flashfloods)  Seasonal forecast (DCLIM): use of 3D analyses from the high resolution global ocean - MyOcean - for initializing seasonal forecast system, run operationally by DCLIM/Météo France (coupled model ORCA025/ARPEGE Climat)  Surface drift, « search and rescue », security at sea (DPREVI/MAR) : use and evaluation of surface currrents - MyOcean- in the operational drift model from Météo-France (MOTHY)
