Abstract

Endeavors to reduce greenhouse gases have been made in all of the world. Nitrous oxide, N2O has not widely been recognized for a greenhouse gas. Some investigations to search the emission sources of N2O and to establish the decomposition method of N2O have just been started. We have continuously monitored atmospheric concentration of N2O at our center of Nagoya University. By the timing correlation analysis of the monitoring data of N2O and those of other greenhouse gases, we tried to find their correlations and identify the emission sources of N2O. In this paper, the results of our study on auto correlations and cross correlations of N2O with other greenhouse gases, CO2 and CH4, and climate parameters are reported. As a result, it becomes clear that though N2O concentration changes slowly and an amplitude of the change is very small in comparison with CH4 and CO2, all of them shows the same periodicity at 1 day. Moreover, an increase in N2O concentration of summer and a dependence of N2O concentration on wind direction were found.
