Variables d'état utilisées dans le module ECOMARS (version de base)
===================================================================
 * Les variables d'état sont définies dans le modèle MARS dans le fichier variable.dat :ref:`doc_variabledat`. 
 * Examples of variable data files are given in **$HOMEMARS/../EXAMPLES/** 
    * For ECOMARS : option 1 : **variable_biolo_opt1.dat**  
    * for ECOMARS : option 2 : **variable_biolo_opt2.dat**

 * La liste des variables utilisées avec l'**option 1** est :
