conc_mod.F90 @ 3205

Last change on this file since 3205 was 3185, checked in by csegonne, 2 years ago

MARS PCM:

conc_mod.F : Added new subroutines init_r_cp_mu and update_r_cp_mu_ak to replace initialization of rnew, cpnew, mmean and akknew as constants and their update if callthermos or photochem (same update as in concentrations.F) that were done in physic_mod.F.
rnew, cpnew, mmean and akknew are now protected meaning they cannot be modified anywhere in the model other than in conc_mod.F .
concentrations.F has been removed.
Knowing where rnew, cpnew, mmean come from is now more explicit. These modifications respond to the need expressed in ticket #90.
