This module contains process rates and utility functions used by the MG microphysics. More...
Original MG authors: Andrew Gettelman, Hugh Morrison Contributions from: Peter Caldwell, Xiaohong Liu and Steve Ghan
Separated from MG 1.5 by B. Eaton.
Separated module switched to MG 2.0 and further changes by S. Santos.
Anning Cheng changed for FV3GFS 9/29/2017 added ac_time as an input
