Validation Tests
  1. All snow tracers on (30percent wind redistribution scheme, dynamic snow grain radius with rsnw_fall = 125 um, hs_ssl = 0.005 m ) and 5 snow layers:

Stephen Price7/29/19Note that these physics are currently off by default. Deciding whether or not to turn them on by default for v2 will require additional testing / tuning / validation as part of the fully coupled system.
