surf_land_orchidee_noz0h_mod.F90 @ 2793

Last change on this file since 2793 was 2571, checked in by jghattas, 8 years ago

Interface LMDZ/ORCHIDEE :

copied previous default module surf_land_orchidee_mod.f90 into surf_land_orchidee_noz0h.f90. This interface can still be compiled if adding cpp key ORCHIDEE_NOZ0H
modified default interface by adding z0h as output from ORCHIDEE.
added comments in each module surf_land_orchidee_xxx of compatiblity with ORCHIDEE.
all modules surf_land_orchidee_xxx now send back z0h and z0m to surf_land_mod. But note that z0m and zOh are different only in the new default version surf_land_orchidee_mod.f90. In the old interfaces, z0h is a copy of z0m.

cosp : some small changes to be able to compile with gfortran

5	! This module controles the interface towards the model ORCHIDEE.
6	!
7	! Compatibility with ORCHIDIEE :
8	! This module is compiled only if CPP key ORCHIDEE_NOZ0H is defined.
9	! This version can be used with ORCHIDEE/trunk revision 2961-3525.
10	! It is possible to use this interface with later versions of ORCHIDEE/trunk than 3525 but
11	! in that case the option ROUGH_DYN=y in ORCHIDEE should not be set.
12	! This interface can also be used with ORCHIDEE/trunk revision 1078-2960 if changing
13	! coszang=yrmu0 into sinang=yrmu0 at 2 places later below in this module.
