The data set basically contains airborne and dropsonde measurements of the AWI-campaign “SpringTime Atmospheric Boundary Layer Experiment (STABLE) that were performed using the POLAR 5 research aircraft to observe the vertical structure of the lower troposphere and boundary layer modifications during marine cold-air outbreaks (MCAOs). Such MCAOs are typically characterized by advection of very cold air masses originating from the sea ice covered ocean over a relatively warm water surface and are thus often associated with strong atmospheric convection. In this data set, meteorological measurements from four days (4, 6, 7, and 26 March 2013) are included, all performed over the marginal sea ice zone and over the open ocean in the Fram Strait region north and west of Svalbard. All research flights of 5-6 hours duration started and ended at Longyearbyen airport, and the measurements provided here were conducted during aircraft vertical profiles and by dropsondes. The observations covered an area between about ...
