Tethered balloon-borne measurements of liquid cloud water presence during flight 28 (PS122/4_48-140)

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. (in review). The data processing is described in Pilz et al. (in preparation). The present dataset covers the presence of cloud microphysical particles measured by the video ice particle sampler on 5 flights between 29 June and 27 July 2020. Since no cloud ice crystal was identified during the flights, the retrievals of the instrument were used to flag the presence of liquid cloud water.系留气球系统BELUGA（Balloon-bornE moduLar Utility for profilinG the lower Atmosphere，用于低层大气探测的模块化气球载荷平台）在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航段中开展作业。该气球于中心观测区的气球场站起飞，作业点位紧邻极星号（RV Polarstern）科考船（Shupe等，2022，《Elementa》）。气球搭载的载荷组件包括扩展型气象探测套装、超声风速仪组件、宽带辐射探测组件、视频冰粒采样器（Video Ice Particle Sampler）以及立方体型气溶胶测量平台。Lonardi等（审稿中）对本次综合观测的应用价值进行了综述。Pilz等（待刊）详述了本数据集的数据处理流程。本数据集涵盖2020年6月29日至7月27日期间5次飞行任务中，由视频冰粒采样器测得的云微物理粒子数据。由于本次飞行任务中未识别到云冰晶，因此采用该仪器的反演结果来标记液态云水的存在。
