Examining the Impact of Nitrous Acid Chemistry on Ozone and PM over the Pearl River Delta Region

<table>Average relative reduction factor (RRF) for ozone is due to 25% VOC emission reduction using simulation cases CB05 and HONO_<i>S/V</i>. The major cities over PRD are ordered by longitude from west to east (see Figure <a href="../fig1/">1</a>): JM: Jiangmen, ZS: Zhongshan, FS: Foshan, ZH: Zhuhai, Ma: Macau, GZ: Guangzhou, DG: Dongguan, SZ: Shenzhen, TW: Tsuen Wan, and HZ: Huizhou.</table>
