Tethered balloon-borne measurements of meteorological and aerosol microphysical properties during the Arctic melt season 2024, flight AIDA_BELUGA_20240603_15@en

As part of the AIDA campaign (Aerosol variability and interaction with ambient conditions based on small-scale vertical and horizontal distribution of Arctic measurements), vertical profiles of meteorological and aerosol particle properties were obtained using the tethered balloon system BELUGA (Balloon-bornE moduLar Utility for profilinG the lower Atmosphere). Measurements were carried out between 19 May and 7 June 2024 at the Arctic research station Ny-Ålesund. In total, 23 flights were conducted on 8 days, reaching altitudes of up to 1300 m. The observations provide detailed information on aerosol microphysics in the lower Arctic atmosphere and support model evaluation and development. The dataset includes measurements from the Turbulence Meteorological Probe (TMP) as well as two interchangeable aerosol instruments: the Cubic Aerosol Measurement Platform (CAMP) and the mSEMS Box (Miniaturized Scanning Electrical Mobility Sizer Box). The aerosol systems were mounted 10 m below the TMP on the tether line and provide aerosol particle number concentrations and particle number size distributions along the vertical profiles本数据集隶属于AIDA研究计划（即基于北极小尺度垂直与水平分布观测的气溶胶变异性及其与环境条件的相互作用，Aerosol variability and interaction with ambient conditions based on small-scale vertical and horizontal distribution of Arctic measurements）。研究团队使用BELUGA系留气球系统（Balloon-bornE moduLar Utility for profilinG the lower Atmosphere，即低层大气探测模块化气球载荷），获取了气象参数与气溶胶粒子特性的垂直廓线数据。本次观测于2024年5月19日至6月7日在北极新奥尔松研究站（Ny-Ålesund）开展，总计在8个观测日内完成23次升空探测，最大探测高度达1300米。本次观测获取了北极低层大气气溶胶微物理过程的精细观测数据，可为大气模式的评估与研发提供重要支撑。本数据集包含湍流气象探针（Turbulence Meteorological Probe, TMP）以及两套可互换气溶胶探测仪器的观测数据：立方气溶胶测量平台（Cubic Aerosol Measurement Platform, CAMP）与微型扫描电迁移率粒径谱仪箱（mSEMS Box, Miniaturized Scanning Electrical Mobility Sizer Box）。上述气溶胶探测系统挂载于系留绳上，距湍流气象探针下方10米处，可同步获取垂直廓线上的气溶胶粒子数浓度与粒子数粒径分布信息。
