摘要
The first multi-oxygen isotopic analysis of nitrous oxide samples from the lower stratosphere has a mass-independent composition. This study extends the results from tropospheric nitrous oxide samples. Measurements are reported from two 8 - 12 km altitude airplane flights from New Zealand to the Antarctic in June and October 1993. The observed isotopic results strengthen the previous argument that an atmospheric process, source, sink, or exchange reaction, involving nitrous oxide must exist in the atmosphere, and they further define its signature.
