NOTE: Modified to allow other microphysics packages (e.g. CARMA) to do ice microphysics in cooperation with the MG liquid microphysics. This is controlled by the do_cldice variable.
If do_cldice is false, then MG microphysics should not update CLDICE or NUMICE; it is assumed that the other microphysics scheme will have updated CLDICE and NUMICE. The other microphysics should handle the following processes that would have been done by MG:
This option has not been updated since the introduction of prognostic precipitation, and probably should be adjusted to cover snow as well.
