Abstract:
A new indicator with temperature dependence of the NO3 loss frequency, was developed to study the contribution of NO3 to the oxidation of monoterpenes and NOx removal in the atmosphere. The new indicator arises from the temperature dependence of kinetic constant. The new indicator was applied to data of observation based on differential optical absorp-tion spectroscopy system on the outskirts of Hefei, China. According to the findings, the contribution of monoterpenes to the loss of NO3 was 70%~80%.

摘要:
利用差分吸收光谱系统得到了大气NO3、NO2和O3的浓度,基于NO3损耗率和温度关系,获得了一种判定NO3对于VOCs的大气氧化能力和清除大气中NOx能力的新指示剂,该指示剂用动力学常量和单萜烯释放速率与温度关系来研究NO3的损耗率.新指示剂应用于研究合肥郊区外场观测的NO3的氧化能力,分析结果表明,在观测期间单萜烯对于NO3的损耗贡献约为70%~80%.
