Purpose: Nitrous oxide (N2O) is an important greenhouse gas. In troposphere, N2O absorbs terrestrial thermal radiation and thus contributes to greenhouse warming of the atmosphere. On a per-molecule basis, N2O is about 200 times more powerful than carbon dioxide: it has been calculated that an increase of 0.2 to 0.3 % in N2O atmospheric concentration would contribute about 5% to the supposed greenhouse warming. N2O is also involved in the depletion of the ozone layer in stratosphere which protects the biosphere from the harmful effects solar UV radiation.

Advanced Global Atmospheric Gases Experiment (AGAGE), and its predecessors (the Atmospheric Life Experiment, ALE, and the Global Atmospheric Gases Experiment, GAGE) have been measuring the composition of the global atmosphere continuously since 1978. The AGAGE is distinguished by its capability to measure over the globe at high frequency almost all of the important gases species in the Montreal Protocol (e.g. CFCs and HCFCs) to protect the ozone layer and almost all of the significant non-CO2 gases in the Kyoto Protocol (e.g. HFCs, methane, and nitrous oxide) to mitigate climate change

Statement

N2O:

Nitrous oxide is measured by using a customized GC-ECD (Agilent 6890N); separation is performed on a double column system (precolumn/backflush and analytical column, both Hayesep Q), isothermically. Length of run is 15 min long. Each ambient air sample is bracketed with calibration runs. The standard are based on NOAA2006 scale.
