Diffusion Coefficient Scheme?



I'm running 3 nested domains. I run real.exe and it says it successfully completes. Once I run wrf.exe, it stops quickly and I get an error: Please choose diffusion coefficient scheme. My rsl.error files now have the same error as the wrf.out files. What in the namelist.input is that referring to?

I've included copies of my namelist.input and wrf.out.

This error means that you need to assign a value to 'km_opt' in your namelist file. You can find the options listed in the namelist section of the WRF Users Guide. I agree the messaging is not clear in that error. I'll make a note to fix that.
