Abstract

Snow is a scattering-dominated medium whose scattering is independent of wavelength at 350 600   nm . The attenuation of solar radiation in snow can be used to infer the spectral absorption coefficient of pure ice, by reference to a known value at 600   nm . The method is applied to clean Antarctic snow; the absorption minimum is at 390   nm , and the inferred absorption coefficient is lower than even the lowest values of the Antarctic Muon and Neutrino Detector Array (AMANDA) experiment on glacier ice: The absorption length is at least 700   m , by comparison with 240   m for AMANDA and 10   m from laboratory attenuation measurements.
