Impact of Residual Water Vapor on the Simultaneous Measurements of Trace CH<sub>4</sub> and N<sub>2</sub>O in Air with Cavity Ring-Down Spectroscopy
Methane (CH<sub>4</sub>) and nitrous oxide (N<sub>2</sub>O) are among the most important atmospheric greenhouse gases. A gas sensor based on a tunable 7.6 μm continuous-wave external-cavity mode-hop-free (EC-MHF) quantum cascade laser (from 1290 to 1350 cm<sup>−1</su...
