problem when run metgrid.exe #2

Dear Dr. Amirhussein I have a question regarding ungrib of ERA5 data; when downloading both surface and level data is it necessary to set the domain to be exactly the same as the domain in the geogrid part of the namelist.wps, Ive selected a domain which is a little larger but I got the following errors when run ./metgrid.exe, do you think it is the cause of this error or could be another issue?

Processing domain 1 of 2 Processing 2015-03-01_00 SFC PL WARNING: Field PRES has missing values at level 200100 at (i,j)=(1,1) WARNING: Field GHT has missing values at level 200100 at (i,j)=(1,1) WARNING: Field PMSL has missing values at level 200100 at (i,j)=(1,1) WARNING: Field PSFC has missing values at level 200100 at (i,j)=(1,1) WARNING: Field SOILHGT has missing values at level 200100 at (i,j)=(1,1) ERROR: Missing values encountered in interpolated fields.

Hi Amin,

Before downloading EAR5 (or FNL, etc.), investigate the lat/lon of your WRF domain and be sure that the ERA5 domain can entirely cover your WRF domain. Otherwise, you will get the error you showed in this issue.

You can plot your WRF domain by PostWRF, to find out the exact extent of your WRF domain.
