    Sulfur hexafluoride (SF 6) is an inert, volatile tracer and has been deliberately added to water bodies to determine k w. Experiments in enclosed lakes showed a good correlation between k w and wind speed and a parameterization of k w developed from these studies predicts a similar global mean (12 cm h −1 ) to that obtained from the radon data.
