   ATLANTIC- EUROPEAN NORTH WEST SHELF- OCEAN PHYSICS REANALYSIS FROM METOFFICEATLANTIC- EUROPEAN NORTH WEST SHELF- OCEAN1985-2014

Institution: Met Office (UK), Copernicus Marine Environment Monitoring Service (CMEMS)
Model: Forecasting Ocean Assimilation Model 7km Atlantic Margin Model (FOAM AMM7); Hydrodynamic calculations were performed by the NEMO system
Resolution: Coverage: European North-West continental Shelf and from 40°N, 20°W to 65°N, 13°E. The model is on a regular lat-lon grid of resolution 1/15° latitude by 1/9° longitude (approximately 7km square). A hybrid s-sigma terrain following coordinate system (following Siddorn and Furner, 2013) with 51 levels is employed in order to retain vertical resolution on the shelf. Products are interpolated onto 24 geopotential 'z' levels based upon the ICES standard depths.
Data assimilated: sea surface temperature data
Assimilation method: 3DVar NEMOVAR
Forcing and relaxation used: ERA-interim winds, atmospheric temperature, and precipitation fluxes; Horizontal boundary conditions were provided by the NOC global reanalysis prior to 1989 and by the GloSea reanalysis thereafter. Boundary conditions in the Baltic sea came from the IOM-GETM model. E-Hype data were used for river inputs.

   ATLANTIC-IBERIAN BISCAY IRISH- OCEAN PHYSICS REANALYSISATLANTIC-IBERIAN BISCAY IRISH2002-2014

Institution: Mercator Ocean (France) => Copernicus Marine Environment Monitoring Service (CMEMS)
Model: NEMO
Resolution: European North East Atlantic, the IBI -Iberian Biscay Irish- area. Horizontal resolution is 1/12° (horizontal resolution ~ 6km), and the vertical one reaches up to 75 z-levels.
Data assimilated: Sea Surface Temperature (AVHRR + Multi-satellites High resolution), together with all available satellite Sea Level Anomalies, and with in situ observations from the CORA3.4 data base, including ARGO floats temperature and salinity measurements.
Assimilation method: SAM2 (Mercator Ocean assimilation system, Lellouche et al., 2013), is based on a reduced-order Kalman filter (the SEEK or Singular Extended Evolutive Kalman filter). An IAU method (Incremental Analysis Updates) is used to apply the increments in the system. The error statistics are represented in a sub-space spanned by a small number of dominant 3D error directions. A 3D-Var scheme corrects for the slowly evolving large-scale biases in temperature and salinity.
Forcing and relaxation used: Forcing and boundaries: the model is forced (every 3 hours) with ECMWF ERA-interim atmospheric products including 10-m wind, surface pressure, 2-m temperature, relative humidity, precipitations, short- and long-wave radiative fluxes. CORE empirical bulk formulae (Large and Yeager, 2004) are used to compute latent sensible heat fluxes, evaporation and surface stress. Solar penetration is parameterized according to a two-band exponential scheme with monthly climatological attenuation coefficients built from Seawifs satellite ocean colour imagery. Lateral open boundary data (temperature, salinity, velocities and sea level) are interpolated from daily outputs from the MyOcean GLOBAL reanalysis eddy resolving system. These are complemented by 11 tidal harmonics (M2, S2, N2, K1, O1, Q1, M4, K2, P1, Mf, Mm) built from FES2004 (Lyard et al., 2006) and TPXO7.1 (Egbert and Erofeeva, 2002) tidal models solutions. Riverine inputs are implemented as lateral points sources with flow rates based on daily observations (when available) and climatological values.

   MEDITERRANEAN SEA PHYSICS REANALYSISMediterranean sea1987-2014

Institution: INGV (Italy), Copernicus Marine Environment Monitoring Service (CMEMS)
Model: NEMO OPA V3.2
Resolution: The model is located in the Mediterranean Basin and also extend into the Atlantic in order to better resolve the exchanges with the Atlantic Ocean at the Strait of Gibraltar. The model horizontal grid resolution is 1/16° (ca. 6-7 km) and the unevenly spaced vertical levels are 72
Data assimilated: The assimilated data include: sea level anomaly, sea surface temperature, in situ temperature profiles by VOS XBTs (Voluntary Observing Ship-eXpandable Bathythermograph), in situ temperature and salinity profiles by argo floats, and in situ temperature and salinity profiles from CTD (Conductivity-Temperature-Depth). Satellite OA-SST (Objective Analyses-Sea Surface Temperature) data are used for the correction of surface heat fluxes with the relaxation constant of 60 W/m2K1
Assimilation method: OceanVAR
Forcing and relaxation used: ERAInterim; Runoff are provided by monthly mean datasets: the Climate Prediction Centre Merged Analysis of Precipitation (CMAP) Data (Xie and Arkin, 1997); the Global Runoff Data Centre dataset (Fekete et al., 1999) for the Ebro, Nile and Rhone and the dataset from Raicich (Raicich, 1996) for the Adriatic rivers (Po, Vjosë, Seman and Bojana). The Dardanelles inflow is parameterized as a river and the climatological net inflow rates are taken from Kourafalou and Barbopoulos (2003).

   MEDITERRANEAN SEA REANALYSISMediterranean sea1955-2014

Institution: INGV (Italy), Copernicus Marine Environment Monitoring Service (CMEMS)
Model: NEMO-OPA version 3.2 and 3.4
Resolution: The model is implemented in the Mediterranean Sea at 1/16° x 1/16° horizontal resolution and 72 unevenly spaced vertical levels (Oddo et al, 2009). It is nested in the Atlantic within the monthly mean climatological fields computed from ten years of daily output of the 1/4° x 1/4° degrees global model (Drevillon et al. 2008).
Data assimilated: The SLA data consist of sea level anomalies referred to a 7-year average (1993-1999) and combine information from different missions (Topex/Poseidon, ERS-1 and ERS-2, Envisat, Jason1 and Jason2), intercalibrated with respect to a reference mission, which is currently Jason2. The temporal coverage depends on the duration of the mission starting from 1992. In situ data: MFSPP (Mediterranean ocean Forecasting System Pilot Project), MFSTEP (Mediterranean ocean Forecasting System Toward Environmental Prediction), SeaDataNet, MEDAR-MEDATLAS and CMEMS In situ TAC (Thematic Assembly Centre).
Assimilation method: OceanVar (Dobricic and Pinardi, 2008); The evolving part of temperature and salinity background error co-variances is represented by seasonal varying
Forcing and relaxation used: The model is forced by momentum, heat and water fluxes computed by bulk formulae adapted to the Mediterranean case, using AMIP data (Cherchi and Navarra, 2007). Heat flux is corrected proportionally to the difference between the model and observed SST (Pinardi et al.2003) with a relaxation coefficient equal to -60 Wm-2 K-1, corresponding to about 2.5 day time-scale over a depth of 3 m. The dataset consists of monthly SST (HadSST1) on regular grid of 1°x1° starting from 1870 (Rayner et al, 2003).Water balance is computed as evaporation minus precipitation and runoff. The evaporation is derived from the latent heat flux. Precipitation is taken from the Climate Prediction Centre Merged Analysis of Precipitation (CMAP) Data (Xie and Arkin, 1997). Runoff is taken from the Global Runoff Data Centre dataset (Fekete et al., 1999) for the Ebro, Nile and Rhone and the dataset from Raicich (Raicich, 1996) for the Adriatic rivers (Po, Vjosë, Seman and Bojana). The Dardanelles inflow is parameterized as a river, and the climatological net inflow rates are taken from Kourafalou and Barbopoulos (2003).
