Abstract Condensation of water molecules from the vapor phase onto liquid water and ice surfaces plays a crucial role in atmospheric processes. In the present study we focus on the accommodation of water molecules from the vapor phase into the bulk crystalline ice phase. Experimental data suggest that the bulk accommodation coefficient decreases with increasing temperature but data from different experiments are spread over a large range of values indicating large uncertainties (Kong et al., 2014; Skrotzki et al., 2013). The results presented here are obtained combining a refined analysis of recent experimental data with molecular dynamics (MD) simulations. MD simulations are specifically used to investigate the role of the disordered interface of ice in depositional growth processes of the crystal phase.
