Mise a jour du simulateur COSP (passage de la version v3.2 a la version v1.4) :

  • mise a jour des sources pour ISCCP, CALIPSO et PARASOL
  • prise en compte des changements de phases pour les nuages (Calipso)
  • rajout de plusieurs diagnostiques (fraction nuageuse en fonction de la temperature, ...)
