TitleThe Growth of Ice Crystals Formed from Frozen Solution Droplets: Laboratory Measurements and Power-law Parameterization
Date2024
AbstractThis data set comprises individual time series for ice crystals grown in an electrodynamic levitation diffusion chamber at temperatures between -61?C and -40?C. Descriptions of the chamber and experimental procedure can be found in Harrison et al. (2016), Pokrifka et al. (2020), and Pokrifka et al. (2023). Experiments were conducted by freezing small (approximately 12.5 micrometer radius) droplets homogeneously with either pure water or a 20% weight-percent sodium chloride (NaCl) solution. All particles were levitated in the diffusion chamber and grown in a constant temperature, pressure, and supersaturation environment. The voltage needed to levitate the particle was recorded as a function of time, then it was normalized by the voltage at the beginning of the experiment. This ratio of the voltages is mass ratio of the levitated particles, which is the mass of the growing particle normalized by its initial mass. The mass ratio time series are archived here. The initial sizes, environmental conditions, and solute for the particles have also been archived. The time elapsed until the particle froze (freezing point) has been recorded and is 0.0 if the particle was frozen before the data collection started. These data are described in an article that is in submission at the Journal of the Atmospheric Sciences (The Growth of Ice Crystals Formed from Frozen Solution Droplets: Laboratory Measurements and Power-law Parameterization, D. Rui, G.F. Pokrifka, A.M. Moyle, and J.Y. Harrington, submitted).
