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

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）于北极气候研究多学科漂流观测站（Multidisciplinary drifting Observatory for the Study of Arctic Climate, MOSAiC）第4航次期间开展作业。该气球于中心观测站的气球场站运行，紧邻极星号科考船（RV Polarstern）（Shupe等，2022，《Elementa》）。气球搭载载荷包括扩展气象套件、超声风速仪组件、宽带辐射组件、视频冰粒子采样器（video ice particle sampler）以及立方气溶胶测量平台。Lonardi等（待刊）对本次联合观测的应用价值进行了综述。数据处理方法详见Pilz等（在编）。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，由视频冰粒子采样器测得的云微物理粒子相关数据。由于本次飞行任务中未识别到云冰晶，因此通过该仪器的反演结果标记液态云水的存在。
