Using Open-Path Dual-Comb Spectroscopy to Monitor Methane Emissions from Simulated Grazing Cattle

Description

Data published in the paper "Using Open-Path Dual-Comb Spectroscopy to Monitor Methane Emissions from Simulated Grazing Cattle". A controlled methane release experiment was performed to determine if dual comb spectroscopy (DCS) can detect methane concentration enhancements above the atmospheric background produced by a typical herd of beef cattle in an extensive grazing system. Open-path DCS was used to measure downwind and upwind methane concentrations from ten point-sources of methane simulating cattle. The assets include all data taken during the field campaign, calculated methane flux, and data explicitly plotted in the paper figures.
