I was able to interpolate by specifying gvcord=hybl:10/pres rather than
sgma:10/pres. But I did not encounter the grid size problem that you're
reporting. For that, I need to know what version of GEMPAK you're using,
and if it was built from source or install from RPM.
GDFILE = data/gempak/model/rap/2017011216_rap130.gem
GDOUTF = out.grid
GDATTIM = first
GVCORD = hybl:10/pres
GLEVEL = 100-1000-50
MAXGRD = 5000
GAREA = 16.2810;-126.1380;55.4814;-57.3806
VCOORD = hght
