  • IFS/HOPE: IFS as atmospheric model coupled to HOPE as ocean model used for seasonal forecasts at ECMWF; climatological sea ice
  • GloSea: Global Seasonal prediction system at the UK Met Office
  • DePreSys: Decadal Prediction System at the UK Met Office: The multi-parameter option (follow this link for a description of the parameters perturbed) with flux correction was used.
  • ARPEGE/OPA4: ARPEGE as atmospheric model coupled to OPA as oceanic model used for seasonal forecasts at MeteoFrance
  • ECHAM5/OM1: ECHAM5 as atmospheric model coupled to OM1 as oceanic model used for seasonal forecasts at Institut fuer Meereskunde/Geomar Kiel
  • ECHAM5/OPA8.2: this is the version of the seasonal forecast model used at INGV in Bologna. A description of the ocean analysis system can be found here.
  • version: refers to the version or cycle of the model used
  • origin: MARS directive to identify the centre of origin of the simulation, see Conventions for Atmospheric Archiving
