Laboratory studies of model aerosol particles suggest that cation valency has little to no effect on the liquid-liquid phase separation relative humidity. Atmospheric aerosol particles composed of inorganic and organic components are able to impact climate through changes in morphology at different relative humidities. The different morphologies can impact the climate through distinctive light scattering and absorbing properties, uptake of water, reactivity with other atmospheric components, effects on air quality parameters, and other effects.
