PEM:

  • Removing completely the ice metamorphism computed by a threshold at the end of the PCM (which was commented).
  • Addition of a module "metamorphism" to compute the PCM frost at the PEM beginning and give it back to the PCM at the PEM end. The frost is considered as the ice given by the PCM "startfi.nc" which is above the yearly minimum. Thereby, metamorphism is performed through this operation.
  • Ice reservoirs representation in the PEM is modernized.
