| 摘 要： | 运用一种新型边界层气溶胶监测激光雷达,在北京丰台区进行了外场实验,探讨了大气边界层内气溶胶消光系数时空分布的特点.实验结果表明:1)冬季北京城区气溶胶源多且变化快;2)北京城区气溶胶污染白天比晚上严重,中午达到顶峰;3)气象条件对气溶胶的扩散和分布影响很大.实验结论对北京城区的环境治理具有较高的参考价值.

| Abstract: | Field experiments were conducted with a new boundary layer monitoring lidar in 2005 winter. The aerosol extinction coefficients are presented, and its space-time distributions are also analyzed. The results indicate that: 1) The sources of aerosol are abundant and multivariate. 2) The aerosol pollution is more severe in daytime than in night, and it is especially severe at midday. 3) The meteorologic condition plays an important role on the diffusion and distribution of aerosol. The results can be referenced for environment management of Beijing. |
