No full textThe aircraft-based experiment KABEG'97 (Katabatic wind and boundary layer front experiment around Greenland) was performed in April/May 1997. The experimental investigations comprised the katabatic wind system over Greenland and measurements of boundary layer fronts (BLFs) over the Davis Strait. Both phenomena are important for the understanding of the climate of the Arctic and the Antarctic. The research aircraft POLAR2 owned by the Alfred-Wegener-Institut (AWI) was based at Kangerlussuaq. During the experiment, surface stations were installed at five positions on the ice sheet and in the tundra. The GPS navigated aircraft was instrumented with the turbulence measuring device 'METEOPOD', allowing high-resolution measurements and the determination of turbulent momentum, sensible and latent heat fluxes. In addition, downward and upward solar and terrestrial radiation and surface temperature were measured; a high-resolution laser altimeter registered surface roughness structures. The GPS dropsonde facility of the aircraft was used for the BLF program over ocean. A total of 13 flights have been performed, three of them were BLF flights. The BLF flights took place during cold air outbreaks over the Davies Strait under conditions of low-level flow parallel to the sea ice edge wind speeds of about 20 m/s. The katabatic wind flights were performed during quite different synoptic situations and surface conditions, and low-level jets with wind speeds up to 25 m/s were measured under strong synoptic forcing of the katabatic wind system.
