Kinetics of Heterogeneous Ice Nucleation on the Surfaces of Mineral Dust Cores Inserted into Aqueous Ammonium Sulfate Particles

Ice freezing of aqueous ammonium sulfate particles containing hematite or corundum mineral dust cores is studied by aerosol flow tube infrared spectroscopy (AFT-IR). The cores induce freezing heterogeneously at temperatures warmer than homogeneous nucleation. Heterogeneous nucleation rates (j) vary...
