光解速率是体现我国大气复合污染特征的关键参数，是不同污染物相互作用的枢纽。NO2的光解速率是对流层臭氧形成关键影响因子之一。然而光解速率与气溶胶相互作用及光解速率对臭氧和二次气溶胶生成贡献的问题仍缺乏深入研究。
Response of tropical stratospheric O3, NO2 and NO3 to the equatorial Quasi-Biennial Oscillation and to temperature as seen from GOMOS/ENVISAT
tropical stratospheric O3, NO2 and NO3 the equatorial Quasi-Biennial Oscillation temperature GOMOS/ENVISAT
2010/9/21
Quasi-Biennial Oscillation signals can be found in the evolution of the three constituents up to at least 40 km. We found that NO3 is positively correlated with temperature up to 45 km in the region w...
