Simulating of lateral snow redistribution processes

Wind-driven snow redistribution

A terrain-based parameterization to account for wind-driven snow redistribution is implemented in openAMUNDSEN. It is a static approach based on topographic openness that applies a redistribution factor on the interpolated solid precipitation field. Details are described in Hanzer et al. (2016).
