If SNOWNC is accumulated grid scale snowfall (snow + ice) what wrf output variable would i subtract to just get ice? I believe this would be equivalent to freezing rain at the surface?
 
It doesn't look like there is a similar variable for just snow. The variable SNOWNC is used in numerous different physics options, and may be calculated a bit differently, depending on what options you're using. I would recommend searching for the variable in the code and looking into the files that you would be using (grep -i snownc */*.F) and look at how it's calculated. You may be able to determine how to break it down from that code.

what about freezing rain?
 
But what is the right formula and variable to calculate the snow fallen on the ground? I would need it in cm, that is the accumulation of snow only
