| 摘 要： | 综合分析了2006年秋季在山东省进行的0.5—8.0μm范围内的大气气溶胶飞机观测的0—4500m气溶胶数浓度垂直分布,初步讨论了气溶胶与温度的关系,并分析了对气溶胶粒子谱的垂直分布情况。结果显示,气溶胶数浓度随高度呈递减趋势,在逆温层附近气溶胶有累计现象;受城市环境的影响,同一区域城市上空或者城市的下风方气溶胶粒子平均浓度都大于上风方;气溶胶粒子谱受不同天气背景的影响,出现不同类型的谱型,随高度的变化,谱型也有很大的变化。

| Abstract: | In order to understand the vertical distribution of aerosol number concentration, the 0.5--0.8 um aircraft aerosol observation data within the height range from 0 to 4.5 km in the autumn of 2006 in Shandong is comprehensively studied. The relationship between temperature and aerosol is discussed and the vertical distribution of aerosol particle spectrum is analyzed. The results show that aerosol number concentrations decrease with the height, while the aerosol accumulates near the inversion layer. The average concentration of aerosol particle over the city or at leeward side of the city is larger than that at the upwind side of the city, and aerosol particles has a wide range of spectrum with height. |
