[gradsusr] unable to get GRAUPELNC from WRF

[Jeff Duda]

It's generated by the microphysics scheme.  You have to be using a
microphysics scheme that outputs number concentration for graupel.  As far
as I know, only the M-Y scheme, Morrison scheme, and possibly the NSSL
2-moment scheme actually do that (as of version 3.4.1).
