Laboratory evidence for volume-dominated nucleation of ice in supercooled water microdroplets
Institut für Physik, Technische Universität Ilmenau, 98684 Ilmenau, Germany
Abstract. We report on measurements of the rate of homogeneous ice nucleation in supercooled water microdroplets levitated in an electrodynamic balance. By comparison of the freezing probability for droplets of radius 49µm and 19µm, we are able to conclude that homogeneous freezing is a volume-proportional process and that surface nucleation might only be important, if at all, for much smaller droplets.
