激光雷达观测北京大气气溶胶的垂直分布

Observation of Aerosol Vertical Distributions by Lidar at Beijing

利用激光雷达对北京2005年4月26—30日大气气溶胶进行了连续观测,对气溶胶光学特性进行了测量和分析,讨论了大气污染物气溶胶和沙尘气溶胶的垂直分布,以及沙尘气溶胶的传输和沉降过程。因此,激光雷达是研究阴霾天气和沙尘天气特征的有效手段。

Continuous observations of aerosols in Beijing were made by polarization Lidar.The optical characteristics of aerosol over Beijing were measured and analyzed from 26 April to 30 April.2005.The vertical distributions of spherical and dust aerosols,and process of dust transmission and deposition were discussed.So,polarization Lidar observation is effective means for research of haze and dust weather characteristic.
