<!--!introduction!--> The interaction of aerosol particles with radiation, clouds, and precipitation is a critical issue in understanding the atmosphere in the mid- and high latitudes of the southern hemisphere. The high abundance of supercooled liquid water in clouds above the Southern Ocean and coastal Antarctica is still puzzling. Atmospheric scientists cannot explain yet to which extent vertical dynamics or pristine aerosol conditions control the persistence of liquid layers. Furthermore, virtually nothing is known about how the abundant supercooled-liquid water influences precipitation formation and the radiative budget. This is especially true in the remote region of Antarctica, where detailed vertically resolved observations of aerosol, cloud, and precipitation are scarce and prevent one to capture the complex cloud processes. We will present a unique observation campaign that will help to address the open questions by contributing a one-year remote-sensing dataset for a coastal ice shelf in ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
