This dataset contains hourly averaged methane measurements taken from Sapper Hill, Falkland Islands Atmospheric Observatory from 2010-2018. Sapper Hill, Falkland Islands Atmospheric Observatory was established by the Royal Holloway Greenhouse Gas Research Group in October 2010 and handed to the British Antarctic Survey AIC group in September 2016 for long term observations of atmospheric mixing ratios. The observatory is located on Sapper Hill overlooking Stanley.

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).
