摘要：

大气区域性污染及其区域输送研究是当前研究的热点问题，2008年北京奥运会的举行为研究北京及其周边大气区域输送提供了机会。主要利用双波长三通道激光雷达和风廓线雷达对颗粒物大气颗粒物区域输送进行研究，介绍了双波长三通道激光雷达的特征及主要参数，讨论了大气颗粒物质量浓度垂直分布的反演方法，并结合风廓线雷达数据论述了颗粒物区域输送的反演，实现了对大气颗粒物输送通量的估算和输送方向的判断。最后，对监测期间典型时间段的大气颗粒物区域输送通量和总量进行估算，并结合SO2实测数据进行了对比分析。

关键词: 激光雷达, 大气颗粒物, 物质量浓度, 颗粒物输送通量

Abstract:

At present, the study on the regional air pollution and atmospheric pollution transport are focal points of research. Beijing 2008 Olympic Games give a good chance to carrying out researches on air pollution and mutual impacts between Beijing and neighboring regions. A new research method for particulate matter transport flux is proposed using lidar and wind profile radar. This method can be used in the monitoring of particulate mass regional transport between city clusters. The structure and technical parameters of the dual-wavelength three-channel lidar are presented, and the atmospheric particulate matter mass concentration vertical distribution and particulate matter transport flux are discussed by combining with the data of wind profile. At last, the transport flux and transport amount of the particulate matter during typical duration are estimated, and which are compared with the SO2 concentration.

Key words: lidar, particulate mass, mass concentration, particulate mass transport flux
