CNRM-CM5 model of CNRM-CERFACS (National Centre for Meteorological Research and Centre Européen de Recherche et de Formation Avancée en Calcul Scientifique)

CNRM-CM5 is the CMIP5 version of the ESM developed jointly by CNRM (Météo-France/CNRS) and CERFACS since 1995. The atmospheric component, ARPEGE, is a specific version of the French weather forecast model developed by ECMWF (IFS) and CNRM, adapted for climate simulations. ARPEGE is available for the scientific community with an exclusive aim of research, within the framework of the “Community Climate Model” project. The oceanic component, provided by CNRS/LOCEAN was updated to Nemo 3.2 for version 5. The SeaIce model, Gelato, developed by CNRM and included from version 2, in 1999, is now at version 5. The river routing scheme TRIP, developed by U.Tokyo and adapted by CNRM, was included in version 3 for CMIP3. The surface scheme SURFEX, which involves the Land Surface scheme ISBA and the sea-flux surface scheme ECUME, was developed by CNRM and included for version 5, for CMIP5. The coupler is OASIS3, developed by CERFACS, and the model workflow is developed at CNRM. For CMIP5, CERFACS undertook decadal simulations, while CNRM took in charge the control, academic, historical, scenarios and paleo-climate simulations.

Main model components

  • ARPEGE: representing the atmosphere
  • SURFEX: representing the land-surface
  • NEMO: representing the ocean
  • GELATO: representing the sea-ice
  • TRIP: representing the river routing
