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 and tropical Atlantic up to 20 degrees S since January 17th 2001. This medium-resolution bulletin (PSY1V2, 1/3 degree; one point computed every 35 km at the equator) gives conditions from the surface right down to the bottom and covers the North and Tropical Atlantic. This resolution is suitable for monitoring ocean circulation on a large scale. 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 first model configuration (1/3 degrees) "Maquette Atlantique Nord" (MNATL) between 20 degrees S and 70 degrees N with 43 vertical levels. No ice model is used. Ice is "diagnostic", i.e., assumed present under a fixed freezing temperature (1.8 degrees Celsius). 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. 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 Medium-resolution North and Tropical Atlantic (PSY1V2, 1/3 degrees) products can be browsed on MERCATOR product web site: "http://bulletin.mercator-ocean.fr/html/welcome_en.jsp"
