Couldn't find a suitable Vtable for RRFS prslev conus 3 km data

[chengbin0228]

I'm trying to run WRF with RRFS input data (https://noaa-rrfs-pds.s3.amazonaws.com/index.html#rrfs_a/) processed through WPS using an existing Vtable. I have tried Vtable. raphrrr; Vtable.NAM; Vtable.RAP.pressure.ncep), but none of them realy worked. The ungrid.exe was done successfully, but metgrid.exe never worked. I've included the logs when I run WPS using Vtable.raphrrr.

At the end of your metgrid.log, the following error messages showed up:

2025-08-25 17:44:21.106 --- WARNING: Field PRES has missing values at level 200100 at (i,j)=(1,1)


2025-08-25 17:44:21.263 --- WARNING: Field GHT has missing values at level 200100 at (i,j)=(1,1)

This indicates that your wrf domain is beyond the area covered by RRFS. Can you adjust your domain and try again?

Thanks for the instruction, I'll adjust my domain and try it again.

Hi Ming,

I tried to download rrfs.t00z.prslev.3km.f***.na.grib2 instead of rrfs.t00z.prslev.3km.f***.conus.grib2 for my simulation domain, this time the ungrid.exe is not working at all. You can find my namelist.wps ungrib.log ungrib_nam.log files attached.

Your log file indicates that the map projection of your input data is not recognized by ungrib.

Can you check the detailed structure of your data, especially its projection, spatial coverage, GRIB parameters, etc.?
