STABLE was led by the Alfred Wegener Institue (AWI) and by the Finnish Meteorological Institute (FMI). The measurements were performed using the POLAR 5 research aircraft, where all research flights of 5-6 hours duration started and ended at Longyearbyen airport. During STABLE, observations focused on the vertical structure of the lower troposphere as well as boundary layer modifications, e.g. during marine cold-air outbreaks and by convection over leads in sea ice. The data set presented here predominantly consists of measurements that were obtained over the Wijdefjorden, which is a North-South oriented fjord with a length of more than 100km in the northern part of Spitsbergen. The measurements were carried out to study the boundary layer structure in the fjord as well as for analyses of the role of the topography on the atmospheric conditions. In its southern part, the fjord was covered by land-fast sea ice until about 72.5km north of the fjord's head. In its northern part, there was open water.descent before landing at Longyearbyen airport, part 215.325917215.435571778.247833378.2537689Deutsche Forschungsgemeinschaft, Bonnhttps://doi.org/10.13039/501100001659171803021Representation of the convective atmospheric boundary layer during cold-air outbreaks in regional models: a joined study based on observations, Large Eddy Simulation and mesoscale modellingGerman Research Foundationhttps://doi.org/10.13039/501100001659268020496TRR 172: ArctiC Amplification: Climate Relevant Atmospheric and SurfaCe Processes, and Feedback MechanismsGerman Research Foundationhttps://doi.org/10.13039/501100001659314651818LU818/5-1, Modellierung und Parametrisierung von durch Rinnen generierter Turbulenz in der atmosphaerischen Grenzschicht ueber antarktischem MeereisGerman Research Foundationhttps://doi.org/10.13039/5011000016595472008Priority Programme 1158 Antarctic Research with Comparable Investigations in Arctic Sea Ice Areas
