【摘要】利用卫星OMI(Ozone Monitoring Instrument)数据获得的长时间序列SO2浓度,分析广州亚运会从申办到成功举办期间珠江三角洲地区近地面SO2浓度的变化过程,以及亚运会举办期间珠江三角洲SO2浓度分布状况。结果表明OMI能够反映近地表的SO2浓度变化趋势,广州亚运会从申办到成功举办期间珠江三角洲地区近地面SO2浓度表现出明显的季节变化,且亚运会期间该地区近地面SO2浓度比以往年同期要低,说明珠江三角洲地区联动的空气质量保障措施明显降低了该地区近地面的SO2浓度。更多还原

【Abstract】 Using the Ozone Monitoring Instrument (OMI) to obtain the long-term SO2 concentration, we analyzed the near-surface SO2 concentration variation before the 2010 Asian Games and the space distribution of Pearl River Delta SO2 concentration during the period of the 2010 Asian Games. It shows that OMI has the ability of monitoring near-surface SO2 concentration variation. Because of linkage air quality guarantee measures in the Pearl River Delta, during the 2010 Asian games, the air quality of Pearl River Delta is better than historical periods.更多还原
