A review of modeling for millimeter wave remote sensing of snow

Millimeter wave sensing presents new problems and prospects in relation to snow. Recognition of the importance and measurement of the particulars of snowpack micro-structure challenge traditional modeling approaches. Simulation methods are examined in relation to the demands of millimeter wave sensing. Distinctive features and critical issues include treatment of near surface micro-structure, medium anisotropy and density, polarization effects, moisture content, and multi-scale surface roughness
