【 摘 要 】

Measuring the density, thermal conductivity, and thermal diffusivity of snow is important for modeling the depth of soil freezing/thawing and water balance of the earth's surface. A method of calculating the thermal diffusivity and snow depth refinement based on mathematical modeling is proposed.
