I am looking for the interface of aerosol module and radiation module in regcm3 Main directory for more than one weeks,but not find it.I want to do something about the aerosol simulation,and need change some radiation parameters for aerosol in the regcm3.There are so many programs and complicated variables in Main directory,I can not find where is the radiation parameters , where is the interface!I find the radiation module comlod3.f and tracer tendencies calculation module.I'd like to konw how the radiative force of aerosol is
