Abstract

Aircraft and balloon in situ measurements of CH4 and HCl using cw distributed feedback (DFB) interband cascade (IC) lasers arereported. 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.
