phys_cosp.F90 @ 2045

Last change on this file since 2045 was 1925, checked in by idelkadi, 11 years ago

Re-ecriture des sorties du simulateur Cosp : Les 3 fichiers mensuel, journalier et haute frequence ne sont plus geres de facon classique par IOIPSL. Les fichiers "includes" ini_hist*COSP.h et write_hist*COSP.h sont supprimes et remplaces par 2 module :
1. cosp_output_mod.F90 : ou sont crees les fichiers et ou sont definis les dimensions et les differents axes.
2. cosp_output_write_mod.F90 : ou sont definis les variables diagnostiques a stocker dans ces fichiers et ou est geree leur ecriture.

L'utilisation d'XIO est prevu (A tester)

Rajouts d'autre variables diagnostiques : sunlit (=0 si nuit et =1 si jour) parasol_crefl (reflectance integree)

Correction du bug dans l'interface avec la physique : On ne veut pas que la distinction entre les nuages convectifs et stratiformes soient prise en compte dans les calculs Cosp. Dans l'interface avec la physique, sont passees en entree pour Cosp, les quantites totales (stratiforme + convective) du contenus en eau et d'autres variables. La fraction nuageuse convective calculee dans la physique est passee en entree pour Cosp dans la version buggee. Elle est remise a 0 dans cette version corrigee.

Mise a jour pour ISCCP : la fraction d'ensoleillement calculee par LMDZ est passee en argument pour Isccp
