Collocated broadband surface albedo and surface type fractions aircraft observations during AFLUX 2019 flight P5_216_AFLUX_2019_1903310801@en

During the AFLUX (Airborne measurements of radiative and turbulent FLUXes of energy and momentum in the Arctic boundary layer) campaign conducted in spring 2019, a downward-looking commercial digital cameras equipped with a 180° - fisheye lens was installed on the aircraft Polar 5. The images were used to derive the surface type fractions of snow/white ice, bare ice, melt ponds, and open water. The data set provides collocated broadband surface albedo, nadir brightness temperature, and surface type fractions along selected flight tracks of six flights.2019年春季开展的北极边界层能量与动量辐射及湍流通量机载测量（Airborne measurements of radiative and turbulent FLUXes of energy and momentum in the Arctic boundary layer，简称AFLUX）科考航次中，研究团队在“波拉尔5号”（Polar 5）科考飞机上部署了一台配备180°鱼眼镜头的下视商用数码相机。所获影像被用于反演雪/白冰、裸冰、融水池及开阔水域的地表类型占比。本数据集提供了6次飞行的选定航迹上的同步匹配宽带地表反照率、天底亮度温度与地表类型占比数据。
