Classical nucleation theory of immersion freezing: sensitivity of contact angle schemes to thermodynamic and kinetic parameters

Luisa Ickes, André Welti, and Ulrike Lohmann

Data sets

Immersion freezing dataset of kaolinite, illite, montmorillonite, microcline and Arizona test dust (ATD) André Welti https://doi.org/10.5905/ethz-1007-76

Short summary

The goal of this study is to find a parameterization scheme for general circulation models to describe immersion freezing with the ability to shift and adjust the slope of the freezing curve compared to homogeneous freezing to match experimental data. We investigated how accurate different formulations of classical nucleation theory reproduce measured immersion freezing curves for different mineral dust types.
