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