Long-term halocarbon observations from a coastal and an inland site in Sabah, Malaysian Borneo

Short-lived halocarbons are believed to have important sources in the tropics, where rapid vertical transport could provide a significant source to the stratosphere. In this study, quasi-continuous measurements of short-lived halocarbons are reported for two tropical sites in Sabah (Malaysian Borneo), one coastal and one inland (rainforest). We present the observations for C 2 Cl 4 , CHBr 3 , CH 2 Br 2 * (actually ~80% CH 2 Br 2 and ~20% CHBrCl 2 ) and CH 3 I from November 2008 to January 2010 made using our μDirac gas chromatographs with electron capture detection (GC-ECD). We focus on the fi... Mehr ...
