what is your input data source and where did you download it?
 
The input data download from the website NCAR RDA Dataset d084001. When I select the parameters, some of them dismatch with my selection, every time the parameters which match the selection are not the same.

I did a subset.
metgrid.log:
2024-11-25 22:23:49.975 --- INFORM: Couldn't find PSFC at level 200100.000000 to fill level 200100.000000 of PRES.

Subsets are notorious for having issues. I would try downloading the whole file and see if that works first.
 
@ lageochy
Please download the whole dataset and try again. Your error message implies that the GFS data you have didn't cover the WRF domain you are running.
 
I downloaded the whole dataset，the error is the same.
and the data subset as follows:
Parameter(s):
Geopotential height
ICAO standard atmosphere reference height
Maximum/Composite radar reflectivity
Pressure
Temperature
Total cloud cover
u-component of wind
v-component of wind
Vertical speed shear
Level(s):
Entire atmosphere
Tropopause
parameters that was selected. If the whole dataset is selected, it remained me it is too large and it is rejected.
