Can clear-sky radiative forcing account for aerosol indirect or semi direct radiative forcing?

Since indirect and semi-direct effect are related with perturbation in clouds, is it not better to use all-sky radiation(with clouds) instead of clear-sky radiation (without clouds)?

What are the possible differences in model outputs of WRF and WRF-Chem apart from atmospheric chemistry and aerosol effects?

I am carrying out PBL parametrization sensitivity study. I am curious to know whether it is beneficial to carry out sensitivity study with WRF-Chem, or the results with WRF alone is sufficient....

Is model spinup required when nudging is done?

I want to perform a WRF simulation, but I am unsure whether I should spinup as I am also doing nudging. So I have these questions basically. 1. Should I do model spinup if I am doing nudging along...
