Regarding the issue of modifying the parameters of WRF.

[zkk2157]

I want to explore the influence of some parameter values in the WRF model on the results. When I adjusted the karman parameter in the ground surface scheme, I found that not only the module_model_constants.F file contained the karman parameter, but also many files included it. At this point, should I only adjust the Karman parameter in the module_model_constants.F file, or should I adjust the karman parameter globally?

This is actually a Fortran question. You don' t need to change KARMAN in each individual codes. You only need to change it in module_model_constants.F, and the change will be passed onto all other codes that use this parameter.
