Abstract

This dataset contains air sample measurements of isotopic d13C methane. The measurements were collected using regular flask samples at Cape Point, South Africa. The samples were analysed Royal Holloway University of London using continuous flow gas chromatography/isotope ratio mass spectrometry (CF-GC/IRMS).

These data were collected as part of the Methane Observations and Yearly Assessments (MOYA) project funded by the Natural Environment Research Council (NERC) (NE/N016211/1).
