Abstract

The transmission of infrared and microwave radiation through falling snow is a subject of interest to the United States Army. The Cold Regions Research and Engineering Laboratories are currently studying the transmission characteristics of various wavelength systems through falling snow. A portable ice crystal replicator which operates unattended has been designed and built for use in this program. Of particular concern in its design was the problem of 'blushing', which results fram the freezing of water on the Formvar plastic material during the replication process. This problem has been at least partially solved in the design of this new instrument. The instrument also incorporates various electronic timing and event recording devices so that the instrument can be incorporated into a larger complex of instrumentation carrying out these transmission studies. A description will be given of the instrument and details presented of ice crystal characteristics that have been observed with the instrument under field conditions.
