Spatio-temporal occurrence, source identification and sea-to-air flux of the greenhouse gas sulfur hexafluoride in the coastal China Seas

In order to discuss the concentration, sources, sinks and radiative forcing of SF6 in the coastal China Seas, we reported concurrent measurements of SF6 in atmosphere and seawater in the YRE (Yangtze River Estuary), YS (Yellow Sea), ECS (East China Sea), and SCS (South China Sea). This dataset contains the original data of SF6 concentrations in atmosphere and seawater in the YRE, YS, ECS and SCS during 2019–2021.
