Abstract

The snow medium is treated as densely packed sticky ice particles following a size distribution. We apply the quasicrystalline approximation (QCA) dense medium theory to calculate the absorption, scattering and emission of snow at multiple frequencies. The correlation of particle position is taken into account by using the Percus-Yevick approximation that can accommodate particles of multiple sizes. The size distribution is discretized so it can be applied to the Percus-Yevick approximation for the cross pair distribution function of particles with different sizes.
