%X We present a novel Monte-Carlo ice microphysics model, McSnow, to simulate the evolution of ice particles due to deposition, aggregation, riming and sedimentation. The model is an application and extension of the super-droplet method of Shima et al. [2009] to the more complex problem of rimed ice particles and aggregates. For each individual super-particle the ice mass, rime mass, rime volume and the number of monomers is predicted establishing a four-dimensional particle size distribution. The sensitivity of the model to various assumptions is discussed based on box model and one-dimensional simulations. We show that the Monte-Carlo method provides a feasible approach to tackle this high-dimensional problem. The largest uncertainty seems to be related to the treatment of the riming processes. This calls for additional field and laboratory measurements of partially rimed snowflakes.
