Abstract

Characteristics of the spatial and temporal distributions of O₃, as well as its source apportionments were all analyzed in Beijing and its surrounding areas by applying the numerical model and comprehensive measurements. The results showed that ozone presented obvious spatial and temporal distribution characteristics and higher concentrations mainly concentrated in the month from May to Sep. There were two pollution belts of ozone in Beijing and its surrounding areas. A pollution zone was mainly concentrated in Beijing-Baoding-northern Shanxi regions, the other was mainly concentrated in Beijing-Tianjin-Bohai areas. The calculated averaged ozone contributions of regional transport (horizontal and vertical transport) to Beijing, Tianjin, Shijiazhuang, Taiyuan, Zhengzhou were 63%, 70%, 74%, 60% and 71% respectively during one heavy air episode of ozone from Aug 11^th to 14^th, 2015. Regional transportation exerted a significant impact to the variations of local ozone.

Key words： O₃ spatial distribution regional transport Beijing and its surrounding areas
