Last change on this file since 1869 was 1534, checked in by musat, 13 years ago

Ajouts CFMIP2/CMIP5

6eme fichier de sortie "stations" histstn.nc qui necessite 2 fichiers: PARAM/npCFMIP_param.data contenant le nombre de points (120 pour simulations AMIP, 73 pour aqua) PARAM/pointlocations.txt contenat le numero, les coordonnees (lon,lat) et le nom de chaque station
flag LOGICAL dans tous les appels histwrite_phy pour pouvoir sortir le fichier histstn.nc

NB: 1) les flags de type phys_ que l'on met dans le physiq.def_L* pour ajouter plus de sorties

necessitent dorenavant 6 valeurs, la 6eme correspondant au fichier histstn.nc

2) par defaut le fichier histstn.nc ne sort pas; pour le sortir ajouter les lignes suivantes

dans physiq.def_L*

### Type de fichier : global (n) ou stations (y)
phys_out_filestations = n n n n n y

introduction de 2 jeux de flags pour les taux des GES; taux actuels avec suffixes _act, taux futurs avec "_per" avec 2 appels au rayonnement si taux "_per" different des taux "_act" (utiles pour diags. CFMIP 4CO2)
flags "betaCRF" pour calculs CRF pour experiences sensibilite proprietes optiques eau liquide nuageuse avec initialisations par defaut; sinon besoin de fichier beta_crf.data
