The present data set is time series data of atmospheric CH4 mixing ratios measured on Hateruma Island, Japan. Hateruma Island is a small ellipse-shaped island in east-west direction with an area of 13 m2, and is the southwestern-most inhabited island of the Japanese archipelago with a population of 500. The monitoring station is located at the eastern tip of the island. Air is sampled from an intake placed on a tower adjacent to the observation station about 37 m above ground level, and the CH4 mixing ratios are measured semi-continuously by using a gas chromatographic system. Hateruma is influenced by the East Asian monsoon, with northerly winds from the continent in winter and southerly winds from the Pacific Ocean in summer. Since Hateruma is a small island surrounded by seas, the influence from local emission sources is negligible.
