  3. WP5 Task T5.4 SST - 03 March 2007 Upgrades : IBI regional systems (PSY2 (MERCATOR) & ESEOAT (PdE) V1) • PSY2V2 (V0) to PSY2V3 (V1) : - Best vertical resolution : 50 z-levels (1m in surface) - New tripolar grid : ORCA 1/12° (OPA 9) - Filtered free surface - CLIO bulk formula to recalculate atm. fluxes - LIM ice model coupling - Upgrades of assimilation : SEEK filter - Validation of the forecasts / satellite and in situ data following the criteria of WP4 V1 IBI PSY2V3 V0 IBI PSY2V2 ECOOP Annual Meeting Athens, 12-15 February 2008

  4. WP5 Task T5.4 Upgrades : IBI regional systems (PSY2 (MERCATOR) & ESEOAT (PdE) V1) • ESEOAT : - Operational system - 4 to 5 km resolution - Tests of different OBC : MERCATOR, FOAM, MFSTEP - Restart strategy to optimize the daily forecast results - Provide OBC for nested systems (METEOGALICIA) - Development of new scheme for real time validation ECOOP Annual Meeting Athens, 12-15 February 2008

  5. WP5 Task T5.4 Upgrades : Iberian coastal area (IST-MOHID & METEOGALICIA-MOHID V1) • IST-MOHID (Western Iberian coast) - Operational system with PSY2 (MERCATOR) OBC - upgrade in assimilation : development of SFEK and SEEK filter in MOHID - Upgrades of run-offs : Tagus, Mondego & Guadiana - Upgrades of atm. forcings : MM5 (9km resolution) - Results available via OpenDAP server - Validation of the forecasts / satellite and in situ data following the criteria of WP4 • METEOGALICIA-MOHID (Galicia coast) - Operational system with ESEOAT (PdE) OBC - Upgrades of run-offs - Upgrades of atm. forcings : heat flux adjustment, interpolation scheme from meteo to ocean grid ECOOP Annual Meeting Athens, 12-15 February 2008

  6. WP5 Task T5.4 Upgrades : Gulf of Biscay and Western Channel (GDGE V1 : IFREMER) Few informations about the upgrades of this system ... • Other initial and boundary conditions have been tested : - PSY2 OBC for TS / Reynaud climatology - MOG2D OBC for SSH / 2D larger IFREMER model (red box in fig) • A finer resolution of 1km is planned • TS (in situ & satellite) assimilation is planned SST GDGE / SST SAFO • Validation of the forecasts in real time / satellite SST (SAFO) ECOOP Annual Meeting Athens, 12-15 February 2008 Daily Bias Daily RMS

  7. WP5 Task T5.4 Upgrades : Irish shelf area (IMI-NE-Atlantic V1 : IMI) • A new rotated domain => boundaries located in deep water, avoiding intersecting either Hatton or Rockall Banks => tidal boundary condition much more accurate => best forecasts of SSH on the Irish coast • 2 runs / week => a best prediction of storm surge sea levels • An OpenDAP server soon ready for the TOP exp. • Output netcdf files in standard COARDS format • Validation of the forecasts in real time / tide gauge data, radiometer SST & ARGO float profiles of TS Radiometer PSY2 IMI-NE-Atl SST ECOOP Annual Meeting Athens, 12-15 February 2008
