Collocated broadband surface albedo and surface type fractions aircraft observations during AFLUX 2019 flight P5_216_AFLUX_2019_1904111501

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.

在2019年春季开展的AFLUX（北极边界层能量与动量辐射及湍流通量机载观测，Airborne measurements of radiative and turbulent FLUXes of energy and momentum in the Arctic boundary layer）科考航次中，Polar 5号科考机搭载了一台配备180°鱼眼镜头的下视商用数码相机。所采集的影像被用于反演雪/白冰、裸冰、融池及开阔水域的地表类型占比。本数据集提供了6条选定飞行航迹上的同步匹配宽带地表反照率（broadband surface albedo）、天底亮度温度（nadir brightness temperature）及地表类型占比数据。
