Aircraft measurements of the boundary layer structure over Nares Strait (Greenland) during campaign IKAPOS with POLAR 5 on 2010-06-22 ...
Gap flows and the stable boundary layer were studied in northwest Greenland during the aircraft-based experiment IKAPOS (Investigation of Katabatic winds and Polynyas during Summer) in June 2010. The measurements were performed using the research aircraft POLAR 5 of Alfred Wegener Institute (AWI, Br...
