Hi

I am having problems running the metgrid.exe. I have the version 4.0 of WPS and geogrid.exe and ungrib.exe have run successfully. But metgrid.exe are not. I have re-compiled whole WPS again, and have the same problem. The input data is from the GFS , the Geographical Static Data is from UCAR and I have two domains.

When running metgrid, it manages to generate some output files from the fisrt domain (met_em.d01.2021-07-06_*.nc), but in a moment it stops and produces the following error without even finishing the first domain:

ERROR: Error in ext_pkg_write_field
Note: The following floating-point exceptions are signalling: IEEE_OVERFLOW_FLAG IEEE_UNDERFLOW_FLAG IEEE_DENORMAL

The last lines in the metgrid.log are:

2021-07-18 23:25:40.438 --- INFORM: Field LANDSEA.mask does not have a valid mask and will not be checked for missing values
2021-07-18 23:25:40.442 --- Initializing output module.
2021-07-18 23:25:40.445 --- ERROR: Error in ext_pkg_write_field

I don't know what's wrong. I will be very grateful for any help.
Attached to this message the files namelist.wps, metrgid.log and geogrid.log.

Thanks!

Hi,
This error typically indicates that you're missing some mandatory surface data. Take a look at this FAQ that states the mandatory fields, and make sure you have them for the surface and soil.
 
Thanks! :mrgreen:

I found the error: the ungrib.exe uses a lot of hard disk and I did not have free space, it gave an announcement of a successful run, but it did not really write the whole intermediate files.
