Description
Change default value for SPRED_PRED
Background
The forcing data is given at dt_force time step (6hours for CRU-NCEP). The precipitations are in mm cumulated on the whole forcing time step (mm/dt_force)
In the driver, only in offline mode, the variable spred_prec define the number of time steps in sechiba on which the precipitation should be distributed.
- If spred_prec = 1, the cumulation of the 6h are distributed in the model during one time step in sechiba.
- If spred_prec = 12, with dt_force=6h and dt_sechiba_30min, the cumulation of the 6h is uniformly distributed over 12 sechiba time steps.
The default value for spred_prec=1.
To be done:
Change the default value for SPRED_PREC to be depending on dt_force and dt_sechiba according to:
if ( dt_force .ge. 3h) then spred_prec = INT(0.5 * (dt_force/dt_sechiba)) ! half of dt_force ! spred_prec = 6 for dt_force = 6h ! spred_prec = 3 for dt_force = 3h else spred_prec = dt_force/dt_sechiba ! uniform endif
