In-flight measurements of ambient methane, nitrous oxide and water using a quantum cascade laser based spectrometer
- 80 Downloads
In-flight measurements of ambient methane, nitrous oxide and water have been made using frequency down-chirped radiation from a compact, pulsed, quantum-cascade laser spectrometer. In three flights from Oxford airport in October 2006 the variations of the concentration of these three trace gases could be measured and related to possible sources in the flight path.
