上海地区夏季臭氧来源追踪数值模拟研究

A Study on Numerical Simulation for Tracking Sources of Ozone for Shanghai Area in Summer Season

基于长三角区域高分辨率排放清单,利用WRF-CAMx-OSAT数值模型,对上海地区夏季臭氧进行了来源追踪分析,结果显示,长三角区域传输是上海臭氧最主要的区域贡献来源,上海城区站点呈现受本地排放影响高于郊区站点的特点。区域人为排放源中,上海地区臭氧主要来自工业和移动源排放,其中城区站点受移动源影响更为显著,郊区站点则受工业源影响较大。

Based on the high resolution emission inventory of Yangtze Delta Region（YDR）, OSAT technology coupled with WRF-CAMx model has been adopted to track the ozone sources for Shanghai area in summer season. It showed that the regional transport of ozone in YDR was a major contributor to Shanghai area, and local emissions in Shanghai impacted its urban spots more than rural ones. Among anthropological emissions, industrial and mobile sources of ozone were dominant in Shanghai area, and mobile ones were evidently the major contributors to urban spots whilst rural spots were affected more by industrial sources.
