Laboratory experiments were carried out to investigate the charge transfer resulting from a limited number of growing ice crystal interactions with a previously rimed target. Crystal sizes up to 200 μm were used for the study. It was observed that the sign of the charge transfer was controlled by the relative growth rates of the interacting particles with the faster growing particle charging postively. The charge transfer magnitude was on the same order as was obtained in multiple ice crystal collision experiments, thus giving confidence to those measurements. ¿ American Geophysical Union 1989
