HALO-(AC)3 – an airborne campaign to study air mass transformations during warm-air intrusions and cold-air outbreaks (ACP/AMT inter-journal SI)(ACP/AMT inter-journal SI)
Editor(s): Andreas Richter Special issue jointly organized between Atmospheric Chemistry and Physics and Atmospheric Measurement Techniques

The purpose of the Special Issue is to publish main results from the airborne field campaign HALO-(AC)3 studying warm-air intrusions and cold-air outbreaks and corresponding air mass transformations. HALO-(AC)3 took place in the area around Svalbard in March and April 2022. The campaign is embedded into a Transregional Collaborative Research Centre ( http://www.ac3-tr.de/) that investigates causes and consequences of the currently ongoing dramatic climate changes in the Arctic.

Review process: all papers of this special issue underwent the regular interactive peer-review process of Atmospheric Chemistry and Physics handled by members of the ACP editorial board.
