I am wondering, if I activate the iclimaaer == 1 option, which means "Use interpolated mixing ratios from chem ICBC" (in the radiation calculation, does it mean, that no chemistry is calculated and for the radiative impact, I must set idirect = 2? Or will the chemistry (e.g. the AERO option) will be activated too? This does not make any sense.

Thanks for clarification

With kind regards

Peter
