A simple model is proposed for the solar albedo of natural snow cover, based on an approximation to the specific surface by a function of grain size and density derived from air permeability measurements. Agreement with limited observational material is good. The model suggests that for grain sizes greater than 1.5 mm, density is the primary factor governing albedo.
