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 CO 2 , CH 4 , NH 3 and H 2 O were observed on the downwind path. Work of the US Government and not subject to copyright.
