一次雄安地区边界层气溶胶和云粒子飞机探测研究

An aircraft detection study of aerosols and cloud particles in the boundary layer of the Xiong’an region

摘要: 随着工业发展，大气污染日益严重，人类对气溶胶的研究也从多方面展开。作为京津冀协调发展的示范区，雄安新区成为新的研究热点地区，为有效分析雄安新区边界层气溶胶的微物理特征，本文选取2023年8月3日飞机观测资料，研究了低空云粒子与气溶胶粒子的分布特征，并根据气溶胶间接效应量化气溶胶与云的相互关系。结果显示，（1）边界层上下云粒子与气溶胶粒子的垂直分布特征及谱分布均存在一定差异：云粒子数浓度在边界层上下相差约2—4个数量级，平均值分别为7.74×10-4 cm-3和3 cm-3，且边界层内数浓度随高度增加而增加，1300—1700 m趋势相反；气溶胶粒子在两个高度层内直

Abstract: With the industrial development, atmospheric pollution is becoming more and more serious, and people's research on aerosols has been carried out from many aspects. As a demonstration area for the coordinated development of Beijing-Tianjin-Hebei region, Xiong'an New Area Becomes New Research Hot Spot Area, in order to effectively analyze the microphysical characteristics of aerosols in the boundary layer of Xiong'an New Area, this paper selects the aircraft observation data on August 3, 2023, and investigates the distribution characteristics of the low-altitude cloud particles and
