surf_land_orchidee_mod.F90 @ 3396

Last change on this file since 3396 was 3391, checked in by oboucher, 6 years ago
Fields can now be passed to ORCHIDEE through surf_land_orchidee. Fields are compressed in pbl_surface_mod and uncompressed in surf_land_orchidee. Cosmetic changes, including in surf_land_mod.
