= ORCHIDEE-HIGH-LATITUDES =

This branch results from the merge of three versions developed by Isabelle Gouttevin (CWRR soil freezing hydrology), Charles Koven (permafrost soil carbon) and Bruno Ringeval (wetlands and methane emissions).


== Notes on the compilation ==

This version needs specific options for compilation (Obelix + Titane only). [[BR]]
If you use modipsl, you have to add the option -mcmodel=medium as an option of the compiler and to link by the option -mcmodel=medium -shared-intel.This option works on sequential and parallel mode. [[BR]]
Without this option, you will have the following error message at the end of the compilation :

In modipsl/util, edit AA_make.gdef and look for the host (lxiv8 for obelix and titane) and modify it.
Look at the following of a correct AA_make.gdef :

After that, execute ./ins_make and compile it from modeles/ORCHIDEE_OL. The compilation should be OK.
