C Purpose:
C    Calcul la difference d'enthalpie et de masse d'eau entre 2 appels,
C    et calcul le flux de chaleur et le flux d'eau necessaire a ces 
C    changements. Ces valeurs sont moyennees sur la surface de tout
C    le globe et sont exprime en W/2 et kg/s/m2
C    Outil pour diagnostiquer la conservation de l'energie
C    et de la masse dans la dynamique.

C the following total value are computed by UNIT of earth surface
C
C d_h_vcol--output-R- Heat flux (W/m2) define as the Enthalpy 
c            change (J/m2) during one time step (dtime) for the whole 
C            atmosphere (air, watter vapour, liquid and solid)
C d_qt------output-R- total water mass flux (kg/m2/s) defined as the 
C           total watter (kg/m2) change during one time step (dtime),
