Abstract
Open-path dual-comb spectroscopy (DCS) is an emerging technique for long open-path measurements across km-scale paths. It provides both broad spectral coverage over hundreds of wavenumbers with high spectral resolution and negligible instrument lineshape. In this chapter we discuss the principle of open-path DCS, provide an overview of the necessary technology and analysis techniques, review field applications including near-IR measurements of urban CO2 emissions, CH4 emissions from drilling and agricultural operations, measurements to a UAV, and recent measurements of VOCs in the mid-IR, and finally provide an outlook especially on how this technique can move to additional spectral regions beyond the near- and mid-IR.Citation
