Snow coefficient
WebSnow 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 WebCoefficients of Friction for Snow An educational, fair use website The coefficient of friction is a dimensionless quantity that quantifies the amount of friction between two surfaces. …
