Hi Jim,

In your file, the Z is not defined correctly:

float Z(Time=1, bottom_top=51, south_north=1001, west_east=1001);
      :coordinates = "XLONG XLAT ZNU";
      :stagger = " ";
      :units = "m";
      :description = "Height";
      :MemoryOrder = "XYZ";
      :FieldType = 104; // int

The correct Z should be like the below, and you need to have z_stag variable 
too:

double z(bottom_top=51);
      :units = "";
      :long_name = "eta values from variable ZNU";
      :positive = "down";
      :_CoordinateAxisType = "GeoZ";
      :_CoordinateAliasForDimension = "bottom_top";
      :_CoordinateZisPositive = "down";

    double z_stag(bottom_top_stag=52);
      :units = "";
      :long_name = "eta values from variable ZNW";
      :positive = "down";
      :_CoordinateAxisType = "GeoZ";
      :_CoordinateAliasForDimension = "bottom_top_stag";
      :_CoordinateZisPositive = "down";
