This project is an experimental and theoretical study of ice crystals in        the antarctic atmosphere and the halos that they produce.  The                  objectives are to make observations of natural halos at South Pole              Station and to sample ice crystals in order to validate computer models         of light refraction and reflection in ice crystals.  Such models have           the potential for the remote sensing of atmospheric conditions.                 Controlled experiments, such as seeding the atmosphere with dry ice,            will produce artificially generated, but simple and well-formed single-         species crystals.                                                                                                                                               The project provides a unique mechanism for examining the crystal growth        and evolution process in the natural atmosphere; it also allows an              examination of the flaling mode (related to residence time) of crystals         in the atmosphere.  It will advance our understanding of the reasons for        the growth of well-formed ice crystals, which is a characteristic of the        antarctic atmosphere, but is not generally observed elsewhere.
