摘要：

Aircraft and balloon in situ measurements of CH4 and HCl using cw distributed feedback (DFB) inter-band cascade (IC) lasers are reported. In the stratosphere and upper troposphere, sensitivity toward CH4 and HCl is better than 10 ppbv (1 s) and 90 pptv (50 s), respectively. These are the first flight measurements of trace gas-phase species using cw DFB IC lasers.
