ORCHIDEE-MEB

Implementation

General idea

It consists to create a supplementary dimension to each variable which correspond to one energy, hydrology budget. In order to do a multi budget over each variable, loop over each subroutine has been chosen. The scheme is implemented such as for each subroutine (i.e. enerbil, diffuco, slowproc etc .. ) in the sechiba file for the global variables.

DO i=1,ncol_enerbil
     pre_subroutine_mc(nmc)
     subroutine(..)
     post_subroutine_mc(nmc)
END DO

#These subroutines are meant to pass variables computed in the subroutine
#to the multi-column variables

pre_subroutine_mc(nmc)
variable=variable_mc

post_subroutine_mc(nmc)
variable_mc=variable

and in each module file (i.e.: enerbil.f90, diffuco.f90 ..etc) for the local variables.

Some tricky points

Some variables such as the wind velocity computed thanks to the roughness or the swnet (which were computed in the driver.f90) have been moved to the file sechiba.f90 in order to take into account the multi-column aspect. The albedo _out was created (the same way as for the z0m_out..(internal fields to outputs)) in order to be able to create an albedo_mc
