    Abstract: Physically based snowpack models are commonly used for the simulation of the snow cover in mountain regions in a high level of detail and process representation. More recently, those models have been adapted to simulate natural and technical snow in ski resorts. Adaptation has been necessary to represent the specific properties of technical snow and snow management practices. This includes the physical description of the snowmaking and grooming processes under consideration of the ski resort infrastructure (snow gun locations and efficiency, water availability, pumping capacity, etc.), but also the associated socioeconomic decisions (when and where to produce snow and to groom). In the frame of the H2020 project PROSNOW, the snowpack models AMUNDSEN, Crocus, and SNOWPACK/Alpine3D will be applied in eight pilot ski resorts across the European Alps for forecasting snow conditions in time scales from days to several months ahead. In our contribution, we present an overview and comparison of these three models including the individual approaches and recent developments for the simulation of natural snow conditions, snowmaking and grooming. We show how individual ski resorts, their infrastructure, and management practices are represented in the models, as well as the approaches for their operational application.
