摘要:

大气中悬浮的颗粒物是评价环境质量的重要指标,激光雷达是获得颗粒物时空分布的重要手段。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,推算PM10质量浓度的垂直分布。风廓线雷达给出了不同高度上风场的变化,可以计算不同高度上颗粒物向城区的输送通量,最终可以估算总的收支。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。

Abstract:

Suspending particles in atmosphere is the important indicator to evaluate the environmental quality. Its spatial and temporal distribution can be obtained by means of lidar. The mass concentration and extinction of particules have a very good correlation. To estimate the vertical distribution of PM10 (particles matter with diameter less than or equal to 10 micrometer), the empirical relationship is established between the extinction and the mess concentration of PM10 measured by TEOM in near ground layer. Combined with wind velocity in different heights which are measured by wind radar, particles transport flux to urban areas is calculated and the total amount of particulates transport is estimated. The long-term continuous monitoring of important industrial source in Beijing is carried out, and the results are presented.

Key words: lidar, transport flux, pollution monitoring, particles
