| 摘要: |
| 日益突出的臭氧（O3）污染已成为继PM2.5之后我国大气污染防治的又一艰巨任务。由于氮氧化物（NOx）、挥发性有机物（VOCs）这2种前体物的减排难度较大，且与O3浓度存在复杂的非线性关系，准确获取O3及NOx、VOCs的时空分布对制定有效的防控措施至关重要。基于卫星遥感可定量反演O3及2种前体物的代表性物种——二氧化氮（NO2）、甲醛（HCHO）及乙二醛（C2、H2、O2）的时空分布信息。面向区域O3污染分析和防控应用，综述了卫星遥感对O3及NO2、HCHO、C2、H2、O2的探测能力，以及利用遥感手段分析区域O3及其前体物的传输。进而从O3与NOx、VOCs关系的角度，分析了利用卫星反演的前体物表征O3生成风险的可行性。最后对卫星在区域O3及其前体物监测方面的前景趋势提出了思考。 |

| Abstract: |
| The increasingly prominent ozone (O3) pollution is the second most arduous task of air pollution control after PM2.5in China. Considering that the emission reduction of nitrogen oxides (NOx) and volatile organic compounds (VOCs) is difficult, and there is a complex nonlinear relationship with O3, so it is important to accurately obtain the spatial and temporal distribution of O3, NOx and VOCs for the formulation of effective prevention and control measures. The spatial and temporal distribution of O3and two representative species of precursors, nitrogen dioxide (NO2), formaldehyde (HCHO) and glyoxal (C2、H2、O2), can be retrieved quantitatively based on satellite remote sensing. Focused on the analysis and control of regional ozone pollution, this paper summarized the detection ability of satellite remote sensing to O3and NO2、HCHO、C2、H2、O2, and analyzed the transport of regional O3and its precursors by remote sensing. The feasibility of using satellite inversion precursors to characterize O3generation risk was analyzed from the perspective of the relationship between O3 NOx VOCs. Finally, the future trend of satellite in regional O3and precursor monitoring was discussed. |
