<!--!introduction!--> <h1>Clear indications of the phenomenon of Arctic Amplification include the above-average increase of the near-surface air temperature and the dramatic retreat of sea ice observed in the last decades. The mechanisms behind these features are widely discussed. Especially the role of clouds and of air mass transports into and out of the Arctic associated with related transformation processes are still poorly understood. Therefore, the HALO-(AC) 3 campaign was performed to provide observations of meridional air mass transports and corresponding transformations in a quasi-Langrangian approach. Three research aircraft equipped with state-of-the-art instrumentation performed measurements over the Arctic ocean and sea ice in March/April 2022. The German High Altitude and Long Range Research Aircraft (HALO), equipped with a comprehensive suite of active and passive remote sensing instruments and dropsondes, was operated from Kiruna, Sweden. The flight pattern covered long distances ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
