AML-1车载测污激光雷达探测大气边界层气溶胶

Measurements of planetary boundary layer aerosols with mobile lidar AML-1

介绍了自行研制用于环境监测的车载式激光雷达(AML-1)系统及典型特点,其在测量气溶胶时不但可以全天候探测,还可以从不同仰角进行测量,对实现连续、实时、大范围监测大气污染有着重要的意义。结合该激光雷达的特点,从垂直、斜程、二维扫描等方面分别给出了该系统探测气溶胶时的典型结果和时空分布图,总结了AML-1车载测污激光雷达系统在测量气溶胶时的优越性和意义。

This paper introduces the typical characteristics of AML-1 mobile lidar, which is the first mobile lidar of China. This lidar can be used to measure aerosols at daytime when receiver angle matches transmitter angle well and high transmission interference filter is used. It also can be used to measure aerosols at different zenith angle because it has 3-D scanning device. All these may have great significance for realizing continual, simultaneous, large-ranged atmospheric pollution detecting. The results show great stability and reliability of AML-1 mobile lidar comparing with other lidars. Typical aerosol profiles and space-time distributing diagrams are shown and discussed at vertical, slant and 2-D scanning aspects.
