Abstract

Near-infrared frequency-comb spectroscopy is used to measure CO₂ absorption over a 2-km outdoor path under well-mixed atmospheric conditions. We compare integrated area, linecenter, and Lorentz widths extracted from Voigt fits to the data with HITRAN. Work of the U.S. government, not subject to copyright.
