Results indicate that the dust-induced albedo reduction decreases by up to 30% as the effective radii of dust particles increase in 1-5 mu m. Nonspherical dust enhances snow albedo reduction relative to spherical dust by up to 20%. Stronger enhancements are obtained for higher dust concentration and larger dust size. Furthermore, the dust nonsphericity-induced enhancement of snow albedo reduction is more pronounced for more-absorptive dust. Finally, we develop a new parameterization for quantifying the dependence of snow albedo reduction on dust nonsphericity and size, and provide a convenient way for assessing the climate impacts of dust in snow.
