- 摘要：基于美国宇航局（NASA）的CALIPSO星载激光雷达L1卫星监测数据，通过分析532 nm总后向散射系数、体积退偏比和色比，对江浙沪地区2009-2014年春节期间大气气溶胶光学与微物理特性进行研究，揭示了江浙沪地区春节期间大气气溶胶散射强度、颗粒规则性与颗粒大小的垂直分布特征.结果表明，燃放烟花爆竹产生的颗粒物主要聚集于对流层中低空，使低层大气散射能力增强、颗粒物尺度增大，使对流层中层大气颗粒物不规则性增强；气溶胶散射能力随高度增大单调减弱，不规则气溶胶在6～8 km高度内占比最大，颗粒随高度增大单调减小；对比各年情况发现，散射能力逐年增强.
- Abstract：Based on the L1 data from the lidar on-board CAPLISO satellite of the National Aeronautics and Space Administration (NASA), the 532 nm total attenuated backscattering coefficient, volume depolarization ratio and color ratio of atmospheric aerosols were analyzed to reveal the distribution of scattering intensity, regularity and size of particles over the area of Jiangsu, Zhejiang and Shanghai during the Spring Festivals from 2009 to 2014. The result showed that particles produced by fireworks mainly gathered in the low and middle troposphere, increasing the scattering intensity and the average size of aerosols in the low troposphere and the irregularity of aerosols in the middle troposphere. The scattering ability of atmospheric aerosols generally decreased with the increasing height, and irregular aerosols accounted for the largest proportion at 6~8 km. The size of aerosols monotonously decreased as altitude increased. The scattering intensity showed an increasing trend.
