Description
Summary:The physical and the optical properties of falling snow have been investigated during a series of winter tests (SNOW experiments). The techniques for measuring the physical properties of falling snow are described and a review of the empirical and the theoretical models for describing the extinction of visible and infrared radiation by falling snow is presented. The utility of these findings for the evaluation of electro-optical sensor performance in a winter environments is examined. Keywords: Electro-optical sensors; Extinction coefficient; Falling snow; Detectors; Winter warfare.
