Six years of continuous CH4 mole fraction and δ13C-CH4 measurements in Heidelberg (Germany) M. Schmidt and A. Hoheisel https://doi.org/10.11588/data/OXKVW2

Short summary

In Heidelberg, Germany, methane and its stable carbon isotope composition have been measured continuously with a cavity ring-down spectroscopy (CRDS) analyser since April 2014. These 6-year time series are analysed with the Keeling plot method for the isotopic composition of the sources, as well as seasonal variations and trends in methane emissions. The source contributions derived from atmospheric measurements were used to evaluate global and regional emission inventories of methane.
