Message:

!!! Important : The microphysical scheme is still a work in progress, and I was trying to fix a bug prior this commit. Ehouarn is planning to review the tracers in the model and to facilitate his work I am now commiting an unfinished version of the microphysical scheme.
For users, the Aurélien Stolzenbach parametrization remains untouched with this commit, meaning that this commit will act as a transparent one for your current simulations. Thanks for your understanding. !!!

Patch note :

First deployment of the microphysical scheme.

Modifications of the Venus Physics

• Removal of the old files / Addition of the new ones linked to the microphysical scheme in the cloud venus folder.
• Modification of cles_phys_mod and conf_phys : Additions of the new keywords used by the microphysical scheme
• Modification of chemparam_mod / phys_state_var_mod : Adding the new tracers and parameters used by the microphysical scheme.
• Modification of phytrac_chimie : Adding the call to the microphysical scheme and computation of the tendencies.
• Modification of physiq_mod : New sedimentation of the microphysical tracers replacing the older ones. Computation of the final mixing ratios of the microphysical tracers. Outputs of the new variables.

New definitions files for the simulations

• New tracer_mic.def, traceur_ion_mic.def
• Update of the differents physiq.def (with a new microphysical sub part)
• Update of the xml files, with the new possible outputs

Miscellaneous

• Fixed a typo in a comment in photolysis_mod

All the information related to the microphysical scheme will be sum-up and updated on the wiki page : ​https://lmdz-forge.lmd.jussieu.fr/mediawiki/Planets/index.php/Venus_PCM_-_Microphysical_scheme
