source: CONFIG/UNIFORM/v5/LMDZOR_v5/GENERAL/PARAM/orchidee.def @ 1759

Last change on this file since 1759 was 1759, checked in by jgipsl, 10 years ago

Adapted LMDZOR experiments to run with new Hydrology version of ORCHIDEE :

  • added file cartepente2D_15.nc needed when starting without restart file (or with old restart file)
  • parameter SOILTYPE_FILE changed name to SOILCLASS_FILE. Keep both parameters in orchidee.def to be compatible with old and new version.
  • added parameter for topography file
