Metseries 3.9.1
Quick explanation of what I think is going:
GFS has recently been upgraded and a number of variables have been added. Notably, additional pressure ranges have been added to Temperature (temp @ 0.4mb).
Because ungrib tries to create a series at each pressure level (Vtable * for level 1), it is picking up the 0.4, which then causes metgrid.exe to fail.
ungrib.exe output snippet (other variables have been removed to make things more readable):
- Code: Select all

ungrib will run successfully. When I then try to run metgrid it will crash with the following error:
WRF_DEBUG: Warning DIM 4 , NAME num_metgrid_levels REDEFINED by var VV 35 34 in wrf_io.F90 line 2588
ERROR: Error in ext_pkg_write_field
I am wondering if anyone else has experienced this issue with the new GFS, and how they solved the issue?
I have looked into editing the Vtable for GFS, however I think I would just like to put specific limits on the pressure levels that are grabbed, and I am unsure how to do that (I have looked at the documentation and played around with g2print.exe to no avail.
Thanks in advanced,
