Hello,

I am using ECMWF (ERA-Interim) data, downloaded from this site: https://rda.ucar.edu/datasets/ds627.0/#access, I have both surface and pressure levels data.

I am running WRF 3.8.1 on Ubuntu 18.0.4 (for real cases) and so far I have only gotten to metgrid.exe, which showed the following error:

WRF_DEBUG: Warning DIM 4, NAME num_metgrid_levels REDEFINED by var RH 22 21 in wr_io.F90 line 2588
ERROR: Error in ext_pkg_write_field
Note: The following floating-point exceptions are signalling: IEEE_OVERFLOW_FLAG IEEE_DENORMAL

and metgrid.exe stopped after making just the first 7 met_em files.

Does anyone have a similar problem ? I am enclosing both the ungrib.log and metgrid.log in case it could help.

Thank you very much,
Klara Ambrozova

Hi,
This error typically indicates that you are missing surface data for the atmospheric fields. Check that for all of your 3D meteorological fields, there is a surface level included. For reference, these are the mandatory fields for running:

This error can also sometimes result when using ECMWF data, and using the calc_ecmwf_p.exe program. Sometimes the ecmwf_coeffs file may be missing level 0 data, and a line may need to be added to the text file in order to allow metgrid to run correctly, after running calc_ecmwf.

Check to see if either of those may be the problem.

mmkamou,
What version of WPS are you using? If it's a version older than v4.0, take a look at this announcement regarding the change in GFS data:
http://forum.mmm.ucar.edu/phpBB3/viewtopic.php?f=94&t=5451

If that's not the problem, did you check on the advice I suggested to the person who originally posted here:

Hi, i have almost the same error as klara_353 :

2019-07-24 10:10:32.367 --- ERROR: Error in ext_pkg_write_field

and metgrid.exe stops after creating ONLY one met_em file.

I have read your suggestions but i could not find any solution.
Can please anyone guide me ??

Miliotis,
Can you attach the gfs file that you are using, along with the Vtable and namelist.wps you're using? Thanks!
 
Hello,thank you, i solved it with some help.
As it seems, i had to download WPS v4.1 and metgrid ran succesfully

Thanks for the answer,
Bill
