Within the framework of (AC)3, four airborne campaigns were conducted in the vicinity of Svalbard to investigate the Arctic airmass transformations during warm air intrusions (WAI) and marine cold air outbreaks (CAO). In this study, we will take a deeper look into the development process of CAOs starting from the marginal sea-ice zone towards the open ocean, using data from active and passive remote sensing instruments. In addition, we will present data from more than 450 dropsondes launched during the HALO-(AC)3 campaign and analyze the development of the vertical profiles along WAIs and CAOs. This is done by using a Lagrangian analysis of the campaign, which delivers same-day and next-day trajectory matches of the HALO flights.
