PM10指能进入呼吸道的质量中值直径小于等于10 μm的颗粒物,它是反应环境质量的重要指标,大气中过多的PM10会严重危害身体健康。激光雷达可以测量大气颗粒物消光系数,近地面颗粒物消光系数与颗粒物质量浓度是相关的,利用震荡天平(TEOM)测量近地面的PM10质量浓度,与雷达测量的消光系数建立经验关系,可以推算PM10质量浓度的垂直分布。风廓线雷达可以获得不同高度上的风向风速,将PM10质量浓度与风场数据二者结合可以计算不同高度上颗粒物向城区的输送通量,最终可以估算污染源向城区的输送总量。使用激光雷达技术对北京重要工业污染源进行了长时间的连续监测,获取了颗粒物输送通量等多种参数,给出了连续监测结果。

PM10 refer to the particles which mass median diameter less than or equal to 10 micrometer. It is an important indicator of environmental quality. Overfull PM10 in air will be harm to health seriously. Lidar (Light Detection And Ranging) can measure the extinction coefficient of atmospheric particulate matter, which has good correlation with mass concentration of particles. Mass concentration of PM10 measured by TEOM(Tapered Element Oscillating Microbalance). The empirical relationship established to estimate vertical distribution of mass concentration of PM10. Wind speed profilers are acquired using wind radar, by which fluxes of PM10 transport can be calculation. An industrial pollution sources (Capital Steel Company) are monitored in a long term. Transport fluxes of PM10 are present.
