Last change on this file since 2930 was 2428, checked in by idelkadi, 9 years ago

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, ...)
