28	c CO2 clouds formation
29	c
30	c There is a time loop specific to cloud formation
31	c due to timescales smaller than the GCM integration timestep.
32	c microphysics subroutine is improvedCO2clouds.F
33	c the microphysics time step is a fraction of the physical one
34	c the integer imicroco2 must be set in callphys.def
35	c
36	c The co2 clouds tracers (co2_ice, ccn mass and concentration) are
37	c sedimented at each microtimestep. pdqs_sedco2 keeps track of the
38	c CO2 flux at the surface
39	c
40	c Authors: 09/2016 Joachim Audouard & Constantino Listowski
41	c Adaptation of the water ice clouds scheme (with specific microphysics)
42	c of Montmessin, Navarro & al.
43	c
44	c 07/2017 J.Audouard
45	c Several logicals and integer must be set to .true. in callphys.def
46	c uf not, default values are .false.
47	c co2clouds=.true. call this routine
48	c co2useh2o=.true. allow the use of water ice particles as CCN for CO2
49	c meteo_flux=.true. supply meteoritic particles
50	c CLFvaryingCO2=.true. allows a subgrid temperature distribution
51	c of amplitude spantCO2(=integer in callphys.def)
52	c imicroco2=50
53	c
54	c The subgrid Temperature distribution is modulated (0 or 1) by Spiga et
55	c al. (GRL 2012) Saturation Index to account for GW propagation or
56	c dissipation upwards.
57	c
58	c 4D and column opacities are computed using Qext values at 1µm.
