ORCHIDEE Parameters
Almost 400 parameters can be set in the parameter file run.def to configure ORCHIDEE. This parameter list is created automatically by scanning all comments on lines beginning with !Config preceding call getin in ORCHIDEE source code. These comments must be on a very strict syntax. Note that the default values listed below can wrong if the comment in the code is wrong. If errors are found in this list, the correction should be done in ORCHIDEE source code. The script to create this list can be found on svn: https://forge.ipsl.jussieu.fr/orchidee/browser/trunk/TOOLS/TOOLS_PARAMETERS
Here is given the list of all the parameters of the trunk rev 4061 are their description and default values :
