Particles Transport Flux Monitoring of Industrial Sources During Beijing Olympic Games by Lidar

Abstract

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
