Well, somewhat blindly jumping in, I just decided to remove the
SPECHUMD line from Vtable.NARR, since I was getting a bunch
of warnings about it, anyway, and I couldn't figure out how to get SPECHUMD
to stop re-defining num_metgrid_levels.  The result is that metgrid.exe
appears to work flawlessly now, as does real.exe, and hopefully
wrf.exe will run successfully (it's sitting in a PBS queue right now).
I did an ncdump on the resulting wrfinput_d01 and can see that the
variables like QVAPOR have non-zero values, implying that the
model is getting moisture from someplace, even though I removed
SPECHUMD from the Vtable.

The question now is, am I insane for removing SPECHUMD from
Vtable.NARR?  Does this seem like a reasonable fix, or should I
be worried about something else?

Thanks,

Don
