Tethered balloon-borne measurements of terrestrial radiation during flight 10 (PS122/4_47-167)

The tethered balloon system BELUGA (Balloon-bornE moduLar Utility for profilinG the lower Atmosphere) was operated during leg 4 of the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC). The balloon was operated from the Balloon Town site in the central observatory, close to RV Polarstern (Shupe et al., 2022, Elementa). Balloon payload included an extended meteorological package, an ultrasonic anemometer package, a broadband radiation package, the video ice particle sampler, and the cubic aerosol measurement platform. An overview showing the value of the combined observation is displayed by Lonardi et al. (submitted). The data processing is described in Pilz et al. (in preparation). The present dataset covers the processed terrestrial irradiances measured by the broadband radiation package on 18 flights between 29 June and 27 July 2020. Terrestrial irradiances were corrected for the time response of the pyrgeometer (6 s) and averaged over 3 s. Flagging of ice and liquid water is provided, based on the analysis of 0.1 Hz pictures of the upper pyrgeometer. Solar irradiances are also available (doi:10.1594/PANGAEA.944232).系留气球系统BELUGA（全称：用于低层大气探测的气球搭载模块化通用平台，Balloon-bornE moduLar Utility for profilinG the lower Atmosphere）于北极气候多学科漂流观测站（Multidisciplinary drifting Observatory for the Study of Arctic Climate，缩写MOSAiC）的第4航次期间投入运行。气球作业地点位于中央观测站的气球镇（Balloon Town）站点，毗邻“极星号”（RV Polarstern）科考船（Shupe等，2022，《Elementa》）。气球搭载的载荷包括一套扩展型气象探测组件、一套超声风速仪组件、一套宽带辐射探测组件、视频冰粒子采样器，以及立方体型气溶胶测量平台。Lonardi等（已投稿）展示了该联合观测的综合价值概述。数据处理流程详见Pilz等（待刊）。本数据集涵盖了2020年6月29日至7月27日期间18次飞行任务中，由宽带辐射探测组件测得的经处理地面辐照度数据。地面辐照度已针对长波辐射表（pyrgeometer）的6秒时间响应特性进行校正，并按3秒间隔取平均。基于对安装于上方的长波辐射表的0.1Hz分辨率图像的分析，数据集提供了冰相与液相水的标记信息。太阳辐照度数据亦可获取（DOI：10.1594/PANGAEA.944232）。
