Study on atmospheric impact of emission sources by simultaneous and real-time measurements of NOx-related compounds

为了评价大气污染物的环境影响，必须在排放源周围的各个位置同时监测它们和/或多化合物。本研究对激光诱导荧光分析仪进行了改进，实现了对NO2气体的多点或多组分测量。通过对真实的城市大气和模拟城市大气的观测，研究了该分析仪对“潜在臭氧（PO）”和NOx相关物种的特性。结果表明，该分析仪能够在第二时间尺度上研究排放源对NO_x-O_3化学的贡献。

To evaluate the environmental impact of atmospheric pollutants, it is essential to monitor them simultaneously at various positions around the emission source and/or for multi-compound. In this study, a laser-induced fluorescence analyzer for NO2 was modified to realize multi-point or multi-compound measurement around the source. Observations of real or modeled urban atmosphere were conducted to investigate the characteristics of the analyzer for' potential ozone(PO)' and NOx-related species. Consequently, it was confirmed that the analyzer was powerful enough to discuss the contribution of emission sources on the NO_x-O_3 chemistry on the second time scale.
