Last change on this file since 5297 was 1144, checked in by jghattas, 16 years ago

Ajoute des variables q2m et t2m comme argument d'entrees dans ORCHIDEE. Pour cela, ajoute de la calcul de ces variables avec stdlevvar avant calcul sur sous-surface.

  • Property svn:eol-style set to native
  • Property svn:executable set to *
