| 中文摘要 |
| 基于美国Aura卫星臭氧观测仪（OMI）提供的对流层NO2垂直柱浓度数据，分析2015年北京世界反法西斯战争胜利70周年纪念活动期间和2016年杭州G20峰会期间NO2柱浓度变化趋势，发现NO2柱浓度能灵敏地捕捉到地面NOx排放量的变化状况.因此，本文利用OMI NO2柱浓度评估"十二五"期间及"十三五"初期我国NOx排放量的变化状况，结果表明，"十二五"期间我国NO2柱浓度降幅为24.98%，NOx减排取得显著成效."十三五"初期，2016年全国NO2柱浓度相比2015年下降3.18%，NOx排放量继续下降. |
| 英文摘要 |
| Tropospheric NO2 vertical column densities (VCDs) from ozone monitoring instrument(OMI) were analyzed to evaluate the decrease in NOx emissions during two special events, 70th anniversary of the end of World War Ⅱ in 2015 and the G20 summit in 2016. Results showed a positive correlation between NO2 VCDs and near ground NOx emissions and verified that the NOx emission control policy during "12th five-year plan" were remarkably effective, with a 24.98% drop in VCDs in five years. At the early stage of "13th five-year plan", in 2016, NO2 VCDs decreased by 3.18% year-on-year, showing a consistent drop in NOx. |
