6. One paragraph description of your model (e.g. abstract from report or paper);
The snow model is a multi-layered one-demensional thermodynamic model. The number of layers is variable and depends on the snow evolution. For each layer, the temperature , density, water content and thickness are calculated. The calculation of the optical properties, albedo and penetration of solar radiation, is based on the CROCUS snow metamorphism laws. Melting, percolation, refreezing and settling are taken into account. The model also includes a snow drift model. Snow erosion threshold depends on snow surface properties such as density, dendricity, sphericity and particles size. The model can be used for seasonal and polar snow packs.
