Surface type classifications from helicopter-borne imagery during a flight PS122/4_45-36 on 2020-06-30

Data include area fractions of sea ice surface types (white ice/snow, bright melt ponds, dark melt ponds, open water, bare ice) obtained from aerial imagery during 29 research flights that were performed within the scope of the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) experiment from May 2020 until end of September 2020. The images were taken every four seconds by fisheye lens cameras (Canon EOS digital) installed on a helicopter or HELiPOD, a towed survey probe. The data set provides additional information about the attitude and geographic location of the helicopter/HELiPOD. Only images that passed the quality checks were included.

本数据集包含北极气候多学科漂流观测站（Multidisciplinary Drifting Observatory for the Study of Arctic Climate, MOSAiC）实验范围内，2020年5月至2020年9月底期间开展的29次科研飞行中，通过航空影像获取的海冰表面类型面积占比数据，涵盖白冰/积雪、亮融池、暗融池、开阔水域、裸冰五类海冰表面。影像由安装在直升机或牵引式测量探头HELiPOD上的鱼眼镜头相机（佳能EOS数码相机）以每4秒一张的速率采集。数据集还附带直升机/HELiPOD的姿态及地理位置相关补充信息，仅纳入通过质量校验的影像对应数据。
