TitleElectrodynamic Levitation Diffusion Chamber Measurements of the Mass Growth of Homogeneously-Nucleated Ice Crystals Grown from the Vapor.
Date2018
AbstractThis data set comprises individual time-series for ice crystals grown in an electrodynamic levitation diffusion chamber at temperatures between -36C and -44C. Descriptions of the chamber and experiments can be found in Pokrifka (2018). Experiments were conducted by freezing small (approximately 10 micrometer radius) droplets homogeneously. Frozen droplets were levitated in the diffusion chamber and grown in a constant temperature, pressure, and supersaturation environment. The voltage ratio needed to levitate the particle was recorded as a function of time and stored in the files archived here. The voltage ratio is identical to the mass ratio of the levitated particles, hence each time-series provides a measure of the mass of the growing particle. The initial size of the injected droplet was measured, and therefore the mass time-series can be calculated from the mass ratio time-series.
