source: LMDZ5/trunk/libf/phylmd/surf_land_mod.F90 @ 2475

Last change on this file since 2475 was 2410, checked in by jghattas, 9 years ago

Added the variable yrmu0(cosine of the solar zenith angle) into ORCHIDEE:

Current version of LMDZ can now be used with ORCHIDEE trunk revisions from rev 2961 and newer. For revision 1078-2960 on ORCHIDEE trunk, a small modification (change coszang into sinang) in surf_land_orchidee_mod.f90 is needed. For older versions than ORCHIDEE trunk revision 1078, the interface in surf_land_orchidee_noopenmp_mod.f90 should be used (add cpp key ORCHIDEE_NOOPENMP).
