Agri-combs: Open-path dual-comb spectroscopy of livestock emissions

Not Accessible

Your library or personal account may give you access

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.
