Mise a jour du simulateur COSP (passage de la version v3.2 a la version v1.4) :

mise a jour des sources pour ISCCP, CALIPSO et PARASOL
prise en compte des changements de phases pour les nuages (Calipso)
rajout de plusieurs diagnostiques (fraction nuageuse en fonction de la temperature, ...)

190	!
191	! TYPE - Set to
192	! 1 for modified gamma distribution,
193	! 2 for exponential distribution,
194	! 3 for power law distribution,
195	! 4 for monodisperse distribution,
196	! 5 for lognormal distribution.
197
198	! PHASE - Set to 0 for liquid, 1 for ice.
199
200	! DMIN - The minimum drop size for this class (micron), ignored for monodisperse.
201	! DMAX - The maximum drop size for this class (micron), ignored for monodisperse.
202	! Important note: The settings for DMIN and DMAX are
203	! ignored in the current version for all distributions except for power
204	! law. Except when the power law distribution is used, particle size
205	! is fixed to vary from zero to infinity, a restriction that is expected
206	! to be lifted in future versions. A placeholder must still be specified
207	! for each.
208
209	! Density of particles is given by apm*D^bpm or a fixed value rho. ONLY specify ONE of these two!!
210	! APM - The alpha_m coefficient in equation (1) (kg m**-beta_m )
211	! BPM - The beta_m coefficient in equation (1), see section 4.1.
212
213	! RHO - Hydrometeor density (kg m-3 ).
214
215	! P1, P2, P3 - are default distribution parameters that depend on the type
216	! of distribution (see quickmbeam documentation for more information)
217	!
218	! Modified Gamma (must set P3 and one of P1 or P2)
219	! P1 - Set to the total particle number concentration Nt /rho_a (kg-1 ), where
220	! rho_a is the density of air in the radar volume.
221	! P2 - Set to the particle mean diameter D (micron).
222	! P3 - Set to the distribution width nu.
223	!
224	! Exponetial (set one of)
225	! P1 - Set to a constant intercept parameter N0 (m-4).
226	! P2 - Set to a constant lambda (micron-1).
227	!
228	! Power Law
229	! P1 - Set this to the value of a constant power law parameter br
230	!
231	! Monodisperse
232	! P1 - Set to a constant diameter D0 (micron) = Re.
233	!
234	! Log-normal (must set P3 and one of P1 or P2)
235	! P1 - Set to the total particle number concentration Nt /rho_a (kg-1 )
236	! P2 - Set to the geometric mean particle radius rg (micron).
