# Thermodynamic properties of chemical species used in the cloud microphysics processes.
# Each condensible specie that should be treated by the model must be entirely described
# here.

# PARAMETER | DESCRIPTION
# ----------|-----------------------------------------------------------------------------
#  name     | Specie name, should be the same as the section name
#  mas      | Molecular weight      [kg]

### List of actual species to be used in the model :
### WARNING : The list of species specified here should be ordered :
###           In the model, ice tracers as well as condensible gazs species must 
###           have the same index.
