| Outline of Final Research Achievements |
The purpose of this study is the development of the measurement instrument of NO3 and N2O5, correlated with the loss process of NOx in troposphere in nighttime, by Incoherent Cavity Enhanced Absorption Spectroscopy (IBBCEAS), and the quantification and the validation of the loss amount of NOx in nighttime.
In actual, this study can not be accomplished due to the big problem for the development of the instrument. But it is possible to detect the nitrous acid and glyoxal, related with the process of the formation of the photochemical oxidant and secondary species while it have been difficult to detect in troposphere, by IBBCEAS due to the improvement and acquisition of the knowledge of the instrument.
