Short summary
In this study, we developed and applied a mobile instrument set-up to determine the carbon isotope source signature by measuring the plume of different methane sources. Therefore, we carefully characterised the analyser especially with regard to cross sensitivities of the gas matrix. During 21 field campaigns we determined mean carbon isotope values of three dairy farms, a biogas plant, a landfill, a wastewater treatment plant, an active deep coal mine and two natural gas facilities in Germany.
