AbstractDual-comb spectroscopy (DCS) provides broadband, high-resolution, high-sensitivity amplitude and phase spectra within a short measurement time, thus holding promises for atmospheric spectroscopy. However, previous research has been limited to measuring over open-air paths of about 20 km. Here, by developing a bistatic set-up using time–frequency dissemination and high-power optical frequency combs, we implement DCS over a 113 km turbulent horizontal open-air path.
