Hi all,

I am running a 5 yr WRF-Chem simulation that includes dust. About 6 months into the simulation the run crashes because the calculated refractive index threshold is exceeded. According to this website (https://ruc.noaa.gov/wrf/wrf-chem/FAQ.htm) the solution is to increase the threshold in the module_optical_averaging.F file and recompile WRF.

I have done this several times and each time that I have done this none of the changes that I make to the module_optical_averaging.F file do not take hold. The model crashes in the same spot with the same error. Even though the changes that I made to the threshold are still there when I check the module_optical_averaging.F file. Is there a step that I am missing to get the changes to take hold?

I am using WRF-Chem V3.8. I have also run the same 5 yr period without dust and the simulation finishes with no issues. Any help is appreciated.

Hi Marcus,

So you get the same error (same threshold exceeded?)

You should not have to do this, but you can try deleting module_optical_averaging.o & module_optical_averaging.f90 and then recompiling. You can also try putting in a simple print statement to ensure your changes have been compiled.
