Last change on this file since 2090 was 1996, checked in by emillour, 6 years ago

Mars physics:

Turn watersat into a module.

CO2 cloud updates:

compute co2 condensation tendencies in the co2 cloud scheme and pass them on to vdifc (for tests; they might not be needed) and adapt newcondens.

	28	c This routine is used to form CO2 clouds when a parcel of the GCM is
	29	c saturated. It includes the ability to have supersaturation, a
	30	c computation of the nucleation rates, growthrates and the
	31	c scavenging of dust particles by clouds.
	32	c It is worth noting that the amount of dust is computed using the
	33	c dust optical depth computed in aeropacity.F. That's why
	34	c the variable called "tauscaling" is used to convert
	35	c pq(dust_mass) and pq(dust_number), which are relative
	36	c quantities, to absolute and realistic quantities stored in zq.
	37	c This has to be done to convert the inputs into absolute
	38	c values, but also to convert the outputs back into relative
	39	c values which are then used by the sedimentation and advection
	40	c schemes.
[1685]	41	c CO2 ice particles can nucleate on both dust and on water ice particles
	42	c When CO2 ice is deposited onto a water ice particles, the particle is
	43	c removed from the water tracers.
[1818]	44	c Memory of the origin of the co2 particles is kept and thus the
	45	c water cycle shouldn't be modified by this.
[1922]	46	c WARNING: no sedimentation of the water ice origin is performed
[1685]	47	c in the microphysical timestep in co2cloud.F.
[1617]	48
	49	c Authors of the water ice clouds microphysics
	50	c J.-B. Madeleine, based on the work by Franck Montmessin
	51	c (October 2011)
	52	c T. Navarro, debug,correction, new scheme (October-April 2011)
	53	c A. Spiga, optimization (February 2012)
	54	c Adaptation for CO2 clouds by Joachim Audouard (09/16), based on the work
	55	c of Constantino Listowski
[1818]	56	c There is an energy limit to how much co2 can sublimate/condensate. It is
	57	c defined by the difference of the GCM temperature with the co2 condensation
	58	c temperature.
[1816]	59	c Warning:
	60	c If meteoritic particles are activated and turn into co2 ice particles,
	61	c then they will be reversed in the dust tracers if the cloud sublimates
