A fix for this bug is now available on the WRF Users Page.

http://www2.mmm.ucar.edu/wrf/users/wpsv3.8/known-prob-3.8.1.html

As Eric Rogers mentioned, the actual problem was in NCEP's g2lib which is used by ungrib. The bug causes certain HGT fields to be unpacked incorrectly by ungrib which then caused problems in real.

Thanks to Eric and NCEP for providing the fix.

I am getting an error with real.exe in seemingly random times. I don't actually think it's a CONDUIT problem as I downloaded the awip3d directly and get the same problem.

I think this is a corruption of only the 40km grids as I manually downloaded the 32km awip32 grids from the same time and it did work. Unfortunately, the 32km is not available on CONDUIT and I'd MUCH prefer using CONDUIT NAM grids rather than downloading from NCEP. Anyone have any ideas?
thanks.
