Melissa,
Referring to:
http://cola.gmu.edu/grads/gadoc/pdef.html
http://cola.gmu.edu/grads/gadoc/wrfvars.ctl
I would try 3 things to start:
1) "1 1" in the pdef line:
pdef 310 189 lcc 17.81886 -127.3326 1 1 39.00000 39.00000
-98.00000 20000.000 20000.000
2) "0" for this variable (don't know if it matters?):
TG=>tg 0 t,y,x Ground Temperature [K]
and
3) to keep it as simple as possible, try for just one dataset (no
options template, and change your dset and tdef lines in the ctl file)...
Hope this helps,
Chuck
