!!**** * - compute the explicit microphysical sources
!!
!! PURPOSE
!! -------
!! The purpose of this routine is to compute the sedimentation
!! of chemical species in the raindrops for the Kessler, ICE2, ICE3 and
!! ICE4 cloud microphysical scheme
!! 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_ice.f90
!!
