!!**** * - compute the explicit microphysical sources
!!
!! PURPOSE
!! -------
!! The purpose of this routine is to compute the sedimentation of chemical
!! species in the raindrops for the C2R2 and C3R5 cloud microphysical schemes.
!! The sedimentation rates are computed with a time spliting technique:
!! an upstream scheme, written as a difference of non-advective fluxes.
!! This source term is added to the next coming time step (split-implicit
!! process). see rain_c2r2.f90
