摘要
用微脉冲激光雷达对西藏那曲地区和北京郊区2004年夏季大气对流层气溶胶的光学特性进行了测量和分析,给出了两地区气溶胶消光系数的垂直分布以及那曲地区的大气边界层高度.结果表明:北京郊区大气对流层气溶胶的组分、浓度及粒径分布较那曲地区呈现出较大的不均匀性,那曲地区则具有较好的近地面空气质量.因此,利用微脉冲激光雷达可以实现大气气溶胶的有效测量.
The optical characteristics of aerosol over Naqu and the suburb of Beijing in combination with Micro Pulse Lidar (MPL) were measured and analyzed. The vertical distribution of aerosol extinction coefficients over the Naqu was showed in comparison with the results over the suburb of Beijing and the heights of Planetary Boundary Layer of Naqu are discussed. The results indicates that the components and concentration of aerosol are more uneven in Beijing than in Naqu, and the quality of air is better in Naqu than in Beijing. Consequently, MPL is a useful tool for monitoring aerosol in atmosphere.
