Changeset 2789 for trunk/LMDZ.MARS

Timestamp:

Message:

1d flag "atm_wat_profile" can be used to force atmospheric water vapor profile :

• atm_wat_profile = 0 (default case) : free vapor & ice profiles
• atm_wat_profile = 1 : dry atmosphere for both vapor and ice
• atm_wat_profile = 2 : wet water vapor profile (0.7*qsat for now) and no ice

Also corrected mistake in README file where EM was responsable for 01/07/2022 commit (but it was me).

 "caps" flag is no longer called in surfini.F to set the location of watercaptag.
 It now only affects the temperature of south pole grid cell in co2condens.

+Added "atm_wat_profile" flag in 1d to force dry and wet atmospheric water vapor profiles.
