Radiative Transfer in Falling Snow: A Two-Stream Approximation

Abstract

Light transmission measurements through falling snow have produced results unexplainable by single scattering arguments. A two-stream approximation to radiative transfer is used to derive an analytical expression that describes the effects of multiple scattering as a function of the snow optical depth and the snow asymmetry parameter. The approximate solution is simple and it may be as accurate as the exact solution for describing the transmission measurements within the limits of experimental uncertainties. Keywords: Cold regions; Light scattering; Light transmission; Snow; Winter warfare.
