Greetings everyone. I'd like some help with a problem i'm facing while running wrf.exe. I'll attach my namelist, rsl.error and rsl.out files, since i'm not even able to track down the problem.

Thanks in advance

Hi,
Can you check all of your rsl files to see if you have any CFL errors in them? You can issue the command:

grep cfl rsl*

If any show up, try decreasing your time step to something more like 4xDX.

There are a couple other things that could be causing issues.
1. Domains 3 and 4 are too small. No domain should ever be smaller than 100x100 grid points (e_we X e_sn).
2. Because your domains are small, you probably don't need to use 60 vertical levels. Try to decrease this back to the default value of 45 for each domain.

Take a look at this page that provides best practices for setting up your domain.

Hello again, thanks for the response.
I rerun the model following such instructions, but now it stops with
"ERROR interpolating ozone in Goddard radiation"

Hi, did you manage to solve the error with the Goddard radiation scheme? I am facing the same issue in a CP simulation.

Are you receiving the same error as the original one posted in this thread? If so, please attach your error logs (e.g., if you have rsl* files, please package them together into a single *.tar file and attach that), along with your namelist.input file. Please let us know which version of the model you're using. Will you also please let me know what a "CP simulation" is? Thanks.

Hello and sorry for the late reply. By CP simulation I meant a convection permitting simulation. In any case, the "ERROR interpolating ozone in Goddard radiation" is not longer appearing for me after downloading O3 files with ERA5.
