I'm using ERA 5 reanalysis as initial and boundary condition for my WRF run. I already downloaded the Land, Pressure and Surface level data that generated the met_em files I'm using on WRF but when I execute real.exe, I got an error as refer to the rsl.error.0000.txt. When executing " ncdump -h met_em.d01.2024-11-11_00:00:00.nc". All ERA5 data was downloaded in this website.Single Level, Pressure Level and Land. Please advice on what to should I do with this error. Thank you.

Hi, See this previous post about the same error. Let me know if that explains your case, as well.
 
I believe this is the comment you're referring to from the other post:

I believe this is an issue with the PSFC variable in your met_em* files. When looking at that variable in the file you sent, I see the value ranges from -22602.6 to 28564.5 Pa. So you have quite a negative value in there, in several locations in that file. I would recommend plotting that variable from the raw input data file to see if the value for surface pressure looks correct, to determine whether this is an issue with metgrid, or with the input file, itself.

If you look at your met_em* files, are you seeing any negative or unreasonable values - specifically for the PSFC variable? If so, I wondered if the user in that post's explanation for the problem may be similar to yours.
