Tethered balloon-borne turbulence measurements during the Arctic field campaign AO2018 in 2018 (Balloon_Hotwire_20180909_0950_1102)

The tethered balloon system BELUGA (Balloon-bornE moduLar Utility for profilinG the lower Atmosphere) was operated from an ice floe next to IB ODEN (around 89°37.0' N , 40°46.5'E). The measurements were taken during the AO2018 (Arctic Ocean) - MOCCHA (Microbiology-Ocean-Cloud Coupling in the High Arctic) campaign on 14 days in the period 18 August to 13 September 2018. For this campaign, a 9 m³ helium filled balloon with modular instrumentation was used. This dataset includes measurements of wind turbulence with a hot-wire anemometer (for instrument characteristics and methods see Egerer et al., 2019).

系留气球系统BELUGA（Balloon-bornE moduLar Utility for profilinG the lower Atmosphere，即低层大气探测模块化浮空平台）于紧邻IB ODEN的浮冰处开展作业，作业点位坐标约为北纬89°37.0′、东经40°46.5′。本次测量工作隶属于2018年北冰洋（AO2018）-高北极地区微生物-海洋-云耦合（MOCCHA）科考项目，于2018年8月18日至9月13日期间的14个作业日完成。本次科考项目采用了一款容积9立方米的氦气填充气球，该气球搭载模块化探测仪器。本数据集包含通过热线风速仪（hot-wire anemometer）获取的风湍流测量数据，仪器特性与测量方法详见Egerer等人2019年的研究成果。
