Nitrous oxide is the third most important anthropogenic greenhouse gas in the atmosphere, contributing about 6% to the radiative forcing by long-lived greenhouse gases. In addition to its role as greenhouse gas, N2O also play significant role in ozone (O3) depletion. Its atmospheric abundance prior to industrialization was 270 parts per billion by volume (ppbv). Its current abundance is ~324 ppbv. Over past 10 years, the mean annual growth rate is ~0.8 ppbv year . It is emitted into the atmosphere from natural and anthropogenic sources. The anthropogenic activities have increased the concentration of long-lived greenhouse gases dramatically since industrialization, and altered the composition of global atmosphere, with great implications for current and future climate. Once emitted, the N2O is very stable in the stratosphere; the only known sink is the photooxidation tractions in the stratosphere. These reactions release oxides of N that contributes to ozone depletion. The magnitude of its current and projected future emissions leads to concerns about the timing of the recovery of ozone.
