Sulfur hexafluoride (gaz sf6) emissions in East Asia determined

Much lower uncertainties are due to seasonal variability in the emissions, inversion geometry and resolution, and the measurement calibration scale. Based on the results of these sensitivity tests, we estimate that the total insulating gas emission in East Asia increased rapidly from 2404 +/- 325 Mg yr(-1) in 2006 to 3787 +/- 512 Mg yr(-1) in 2009 and stabilized thereafter.
