Abstract:
Mercator has been providing weekly analysis and real-time nowcast (T0), and forecast (T0+7 days and T0 +14 days) bulletins of the three-dimensional ocean in the North Atlantic and Mediterranean Sea since January 8th 2003. This High-resolution bulletin (PSY2V1; 1/15 degree; one point computed every 5 to 7 km throughout the region of interest; eddy-resolving) covers the North Atlantic and Mediterranean basin. For more information see Mercator Configurations Summary at "http://www.mercator-ocean.fr/html/mod_actu/public/welcome_en.php3" Additional information about the Model: --------------------------------------------------- Mercator ocean system is based on the 8.1 version of the OPA z-coordinates code (Madec et al. 1998). OPA is an incompressible Navier-Stokes primitive- equation model using Boussinesq rigid-lid approximation that describes the temporal evolution of velocity, temperature and salinity in three dimensions. Mixed layer dynamic is ruled by TKE turbulent closure equations (1.5 closure scheme) (Blanke et al. 1993). The ocean model configuration used in this prototype (PSY2) is the high resolution (1/15 degrees) "Prototype Atlantique Mediterranee" (PAM) between 9 degrees N and 70 degrees N with 43 vertical levels with layer thicknesses from 6 meters at the surface to 200 meters at the bottom of the Mediterranean basin and 300 meters at the bottom of the Atlantic ocean. It includes a very simple thermodynamic ice model ('IF' ice model). The bathymetry is processed from the Smith and Sandwell (1997) data base and ETOPO5. Momentum and heat forcings are daily ECMWF forcing. Surface temperature is restored from Reynolds analyses (Reynolds & Smith, 1994), which include satellite and in-situ observations. Surface salinity is restored from climatology. The model is initialized using Reynaud (Reynaud et al. 1998) seasonal climatology. A relaxation to seasonal Medatlas (2002) climatology is also applied below 500 meters in the Gulf of Cadiz to represent Mediterranean Outflow Water. Assimilation Method: -------------------------- The data assimilation method (SAM; Systeme d'Assimilation Mercator) used is the reduced-order optimal interpolation (OI) scheme SOFA (Sub Optimal Filtering of Altimetry) (De Mey and Benkiran, 2002) coupled with the PALM software coupler (PALM group, 2000). The baroclinic component is corrected applying a lifting-lowering method similar to Cooper and Haines method (1996). Data assimilation is stopped along isobaths 500m towards the coast. Sea level anomaly (SLA) from Jason1/ERS2-Envisat/GFO is assimilated along track, once a week. The mean sea surface height (MSSH) used during the assimilation process is the one from Rio et al. (2003) diagnosed from in-situ observations in the Atlantic ocean. In the Mediterranean basin, MSSH is made out of several numerical simulations. Version 1 products assimilates altimetry data (SLA) only, while version 2 products assimilates altimetry and in situ data (SLA, Sea Surface Temperature (SST), Sea Surface Salinity (SSS) and In situ profiles). Mercator bulletins contain a range of parameters selected to depict ocean conditions and dynamics. These include: salinity, temperature, surface currents, zonal, meridian and vertical velocities, transport, sea surface height, mixed layer depth, barotropic height, baroclinic height. "Model: analysis and forecasting" 3D ocean products can be accessed on-line through Mercator Web Products (full domain and zonal animations, whole maps, zonal maps, sections and moorings graphs). For additional product information see "http://www.mercator-ocean.fr/html/produits/description/welcome_en.html". Mercator web products are designed for a wide audience (freely available), while numerical products are files for professional users and are available on a remote server. Please make an e-mail request to products@mercator-ocean.fr Archive bulletins are also available to identify longer-term patterns. Mercator web High-resolution North Atlantic and Mediterranean (PSY2V1, 1/15 degrees) products can be browsed on MERCATOR product web site: "http://bulletin.mercator-ocean.fr/html/welcome_en.jsp" In the Mersea strand1 european project context, Mercator makes available via an DODS/Opendap server its PSY2 high-resolution prototype products since 01/06/2003. Mercator also offers access to its products via the LAS implemented in the Mersea context. Fields provided for the Mersea inter-comparison exercise are daily mean best estimate fields as well as T0+7 forecast. Class1 (2D and 3D oceanic variables), 2 (sections and moorings), 3 diagnostics are provided on the Mercator-Mersea DODS/Opendap (password protected). For more information see "http://strand1.mersea.eu.org/html/strand1/datalinks.html" For more information about DODS/Opendap and Live Access Server (LAS), see Numerical products handbook "http://www.mercator-ocean.fr/html/produits/description/welcome_en.html"
