[Wrf-users] Real.exe Error

[Waylon.Collins]

Dear Users,

Attached is selected output from running real.exe. The run aborted due 
to the following error: "...the interpolating order is too large for 
this few input values". Any idea what specifically caused this problem? 

There was no problem compiling and running the latest version components 
of WPS (geogrid, metgrid, and ungrib) on my system. With regards to I/O, 
I chose the netCDF output format for both geogrid and metgrid, and the 
WPS format for output to ungrib. I successfully compiled the latest 
version (v2.2) of WRF-ARW for real runs. I compiled using pgf90 v6.1-3. 
The gridded data used as input into WPS are output from the NAM 
(WRF-NMM). Further, I used both Vtable.NAM and METGRID.TBL.ARW.

Also attached is selected output from the uname command for my system.

Waylon
