<!--!introduction!--> The Arctic climate is changing at fast pace. The contribution of low-level clouds to Arctic amplification feedback processes remains challenging to quantify as model evaluation requires continuous, high-quality measurements in a demanding environment. Advancing the understanding of governing processes of mixed-phase clouds, ubiquitous in the Arctic, calls for temporally high-resolved measurements of cloud and precipitation microphysical properties as well simultaneous quantification of water vapor amount and profiles in all-weather conditions. Based on instrument simulations, we demonstrate the added value of the G-band Radar for Water vapor profiling and Arctic Clouds (GRaWAC) system for cloud and water vapor observations at an Arctic ground-based and air-borne observation supersite. Currently in final development stages, the GRaWAC system is a worldwide unique FMCW G-band radar with Doppler-resolving capabilities and simultaneous dual-frequency operation.
