Abstract

Near-infrared dual-comb spectroscopy is performed over two open-air paths upwind and downwind from pens containing approximately four hundred cattle. Time- resolved enhancements of CO₂, CH₄, NH₃ and H₂O were observed on the downwind path. Work of the US Government and not subject to copyright.
