TYPE: enhancement
KEYWORDS: NSSL microphysics
SOURCE: external ( Ted Mansell, NOAA)
PURPOSE: modification of NSSL microphsycis
DESCRIPTION OF CHANGES:
(1) Helped performance in sedimentation with flag "do_accurate_sedimentation" to control recalculation of fall speeds when more than one sub-time step is needed (often happens with large time steps and small dz near the ground):
= .true. : recalculates fall speed after each substep (more accurate)
= .false. : (default) reuses fall speeds calculated on the first substep (typical for most schemes), theoretically could cause an occasional glitch, but none seen in practice
(2) Increased maximum mean droplet radius from 40 to 60 microns, which alleviates spurious number concentration increases at low CCN concentration.
