Tethered balloon-borne measurements of meteorological parameters during MOSAiC leg 4 in June and July 2020@en

In the framework of the Multidisciplinary Observatory for the Study of Arctic Climate (MOSAiC) expedition, the tethered balloon system BELUGA (Balloon-bornE moduLar Utility for profilinG the lower Atmosphere) was deployed from a research camp on an ice floe drifting in the Fram Strait in Summer 2020. The BELUGA system consists of a 90 m³ helium-filled balloon with modular instrumentation. The present data set covers the meteorological measurements with an extended radiosonde package on 31 flights with mean altitudes of 1 km between 29 June and 27 July 2020. Lonardi et al. 2022 give an overview of the BELUGA observations during MOSAiC leg 4. A data descriptor by Pilz et al. (in preparation) describe the sensor package and the BELUGA operations in detail.在北极气候多学科观测（Multidisciplinary Observatory for the Study of Arctic Climate，缩写MOSAiC）考察计划框架下，系留气球系统BELUGA（Balloon-bornE moduLar Utility for profilinG the lower Atmosphere，即低层大气廓线探测模块化气球载荷系统）于2020年夏季在弗拉姆海峡（Fram Strait）一处漂流浮冰的科考营地完成布放。该BELUGA系统由容积90立方米的充氦气球与模块化探测仪器组成。本数据集涵盖2020年6月29日至7月27日期间31次探空飞行的气象观测数据，搭载扩展型无线电探空仪（radiosonde）组件，单次飞行平均探测高度达1千米。Lonardi等（2022）对MOSAiC考察第4航次期间的BELUGA观测结果进行了综述。Pilz等（待发表）的数据集说明文档则详细阐述了该探空仪组件及BELUGA系统的运行细节。
