摘要：

基于臭氧监测仪（ozone monitoring instrument, OMI）数据反演得到了京津冀地区2014年11月北京APEC会议前后5期的NO2整层柱浓度，结合HYSPLIT4气流后向轨迹模式对NO2污染物的来源及传输路径进行模拟和分析。研究结果表明: APEC前后京津冀NO2垂直柱浓度空间分布极不均匀，APEC前高值、中值分别分布于京津周边及南部地区，北部及西北处于低值区；APEC期间高值区集中于京津冀南部地区,呈由南到北递减的趋势；APEC后高值区范围向北扩展到京津地区的中南部。APEC期间除京津冀南部的邢台、邯郸地区NO2浓度升高外，其他地区NO2浓度与会前一周相比平均下降42%。气流后向轨迹模式表明APEC前北京地区NO2污染源主要来自于唐山、天津地区，APEC期间主要来自于俄罗斯、外蒙地区，APEC后主要来自于太原及京津冀西南地区。

Abstract:

Five phases ozone monitoring instrument (OMI) NO2 column density data and Back Trajectory Model (HYSPLIT4) were used to simulate and analyze an NO2 pollution event around the APEC meeting, Beijing, November, 2014. The results show that the spatial distribution of NO2 vertical column density was extremely uneven before APEC. The high-value were distributed in surrounding of Beijing and Tianjin, the mid-value were distributed in its south areas, north and northwest is the low value area. The high value concentration in Beijing, Tianjin and the southern region showed a decreasing trend from south to north during APEC; the range of high value area expanded northward to the central and southern areas of Beijing and Tianjin after APEC. Compared with concentration a week ago, density of NO2 in Xingtai and Handan, which are in south of Beijing-Tianjin-Hebei region, had showed a trend of rising, and concentration in another places had fallen 42% during the APEC. According to back trajectory analysis based on HYSPLIT, the import of NO2 pollution comes from Tangshan, Tianjin before APEC. During the period of APEC, the pollution comes from Russia, Mongolia region. After the APEC, Beijing, Tianjin, Taiyuan and the Southwest are the main NO2 sources areas.
