Previous studies have shown mixed results on the potential of light-absorbing particles serving as ice nucleating particles. The composition, sources, and cloud feedbacks of ice nucleating particles remain poorly constrained. There is a need for more accurate analysis of ice nucleation activity in environmental samples.

The existing method for estimating the aerosol mixing state index assumes a binary system of more- and less-hygroscopic components. This assumption may not represent aerosol populations containing intermediate-hygroscopicity species. There is a need to evaluate the performance of this method using a particle-resolved model.

Further studies are needed to investigate the effects of aging processes on the mixing state and ice nucleation abilities of aerosol particles. Research should be conducted to quantify the error in predicting CCN concentration and ice nucleation rates for populations with different mixing states. Studies should be done to explore the potential link between the mixed state of population and particle ice nucleation propensity.
