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。
近日，安光所高晓明研究员团队在光声光谱同时测量大气气溶胶和二氧化氮（NO2）方面取得新进展，相关研究成果以“用于同时测量气溶胶吸收和NO2浓度的基于443nm激光二极管的差分光声光谱仪”为题在线发表于光声光谱领域知名期刊Photoacoustics上。大气气溶胶、NO2是大气主要污染物之一，气溶胶吸收的在线测量仍然是难题之一，光声光谱因其不受光散射影响、探测器不受光波段限制等特点，在测量气溶胶、痕...
