-The alread in PALM-4U implemented 2-moment cloud physic scheme following Seifert and Beheng (2006) was extended with the cloud ice species during the previous project runtime and now contains prognostical parameters of ice crystal number concentration and ice crystal mixing ratio. In addition the microphysical processes of nucleation, deposit growth of ice crytals, and sedimentation of cloud ice are considered. For the validation of the implemented processes simulations based on an idealised case study (Ovchinnikov et al., 2014) of an Arctic mixed phase cloud (figures 1 & 2) have been conducted. The figures show time series of the liquid water  path (LWP) and the ice water path (IWP) for PALM-4U as well as additional LES models with similar microphysics parametrisations for simulations of different ice seed numbers (fig.1: 1000 L-1, fig.2: 4000 L-1). In general, a good agreement with other models can be observed.

 During the project duration the cloud physics will be extended by the snow species where in particular collision processes have to be taken into account (see fig. 3).
