Methane Observations and Yearly Assessments (MOYA): Isotopic d13C methane measurements taken from Zeppelin Observatory

This dataset contains air sample measurements of the ratio between carbon 12: carbon 13 in atmospheric methane (d13C). The air samples measured were taken from an inlet on the Zeppelin Observatory into either flasks, tedlar bags or flexfoil bags. The samples were analysed for the carbon ratio in methane at Royal Holloway University of London using continuous flow gas chromatography/isotope ratio mass spectrometry (CF-GC/IRMS). This data was collected as part of the Methane Observations and Yearly Assessments (MOYA) project funded by the Natural Environment Research Council (NERC) (NE/N016211/1).
