| Research Abstract |
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.
