[Wrf-users] Vtable error

[Eric Altshuler]

Dear Ulas Im,

You need to make a symbolic link to the desired Vtable in your WPS directory before running ungrib:

ln -s ungrib/Variable_Tables/Vtable.GFS Vtable

Also, g1print.exe reads grib files, not Vtables. Run g1print.exe like this:

g1print.exe <your_grib_file>

Hello 



I am trying to run WRF with fnl data. I use Vtable.GFS as the variable table but ungrib.exe crashes not finding the vtable, as fallowing 



*** Starting program ungrib.exe *** 

Start_date = 2007-12-25_00:00:00 , End_date = 2008-02-01_00:00:00 

output format is WPS 

Path to intermediate files is ./ 

ungrib - grib edition num 1 

***** ERROR in Subroutine PARSE_TABLE: 

Problem opening file Vtable. 

File ''Vtable'' does not exist. 

ERROR: ***** Stopping in Subroutine PARSE_TABLE 



On the other hand, when I try to look at the vtable with g1print.exe, I get the following error: 



Copen: File = Variable_Tables/Vtable.GFS 

Fortran Unit = 6948128 

UNIX File descriptor: 3 



---------------------------------------------------- 

rec GRIB GRIB Lvl Lvl Lvl Time Fcst 

Num Code name Code one two hour 

---------------------------------------------------- 

Error trying to read grib edition number in gribsize. 

Possible corrupt grib file. 

Incorrect edition number = 76 

Skipping the rest of the file and continuing. 



***** End-Of-File on C unit 3 





What might be the problem 



Thanks in advance
