Short summary

An annual cycle of mixed-phase ice-formation temperatures in the high Arctic is presented. Ship-based remote sensing with lidar and cloud radar from the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) expedition was used to investigate the impact of surface processes on mixed-phase cloud properties. Surface mixed-layer cloud coupling was derived from radiosonde profiles. Combined with ice nucleating particle filter samples, sea ice concentration, and trajectory analysis an influence of surface processes on cloud properties was found.
