-Addition of the parameter 'CO2cond_ps' (= 1 by default) for 1D. This coefficient controls the surface pressure change. If 'relaxcoef_ps = 1', then surface pressure varies normally. If 'relaxcoef_ps = 0', then surface pressure is kept constant. The ratio of polar cap surface over planetary surface is a typical value (8.3e-4) for tests. To be defined in "callphys.def" so that both PCM and PEM can read it.
