  • Modifications liées au calcul des nouveau sous-fractions
  • Nettoyage de ocean slab : il reste uniquement la version avec glace de mer forcé
  • Nouveaux variables pour distiguer la version et type d'ocean : type_ocean=force/slab/couple, version_ocean=opa8/nemo pour couplé ou version_ocean=sicOBS pour slab

29! This subroutine will make a call to ocean_XXX_noice according to the ocean mode (force,
30! slab or couple). The calculations of albedo and rugosity for the ocean surface are
31! done in here because they are identical for the different modes of ocean.
