PM2.5 Monitoring and Analysis in Beijing Spring in a Dust-Haze Period

Abstract:

The spring is a high incidence of dust-haze season especially in some mega-cities like Beijing. A complete dust-haze has happened from 19th to 24th April, 2013. Based on 3456 copies of PM2.5 concentration data in Beijing’s 24 monitoring points during the whole dust-haze period, and the weather information over the same period, and the correlation analysis on the dust-haze’s formation, continuous and dissipation process, we point out that PM2.5 concentration distribution has the following features in a spring dust-haze weather in Beijing: (1) dust-haze can be happened in strong wind; (2) PM2.5 concentration has a highest or lowest value during the dust-haze process at some monitoring sites (3) the monitoring sites’ PM2.5 concentration difference is bigger, the biggest can reach more than eight times.
