Message:

Ajout de l'option iflag_cloudth_vert=2 developpe par Jean Jouhaud pour l heterogeneite verticale sous maille des
nuages. Pour le moment, l ecart type de la pdf verticale vaut la moitie de l ecart type de la pdf horizontale.
Le iflag_cloudth_vert=1 conserve l heterogeneite verticale telle qu introduite par Arnaud Jam en Avril 2015.
