DMRT-QMS (QCA Mie scattering of Sticky spheres) v0.1 The code supports both active and passive remote sensing of layered snowpack. It is an implementation of the dense media radiative transfer theory, applying the scattering model of QCA Mie of densely packed Sticky spheres. The radiative transfer equation is solved using the discrete ordinate method by eigen-quadrature analysis. Ground roughness is partially taken into account for the emissivity in passive remote sensing and backscatter in active remote sensing. In the snowpack description file, each row describes one snow layer, starting from top, going downwards. Each row contains five columns, specifying the layer_thickness (cm), density (gm/cc), temperature (K), grain_diameter (cm), and stickiness, respectively.
