Stable carbon isotope composition of atmospheric methyl bromide
[1] Methyl bromide (CH3Br) constitutes the largest source of bromine atoms to the stratosphere and plays an important role in stratospheric ozone depletion. However, the CH3Br atmospheric budget remains uncertain. We report the first measurements of stable carbon isotope ratios for atmospheric CH3Br and explore the constraints they provide for the atmospheric budget. The measured dC of CH3Br ra...
متن کاملCarbon isotope fractionation of methyl bromide during agricultural soil fumigations
The isotopic composition of methyl bromide (CH3Br) has been suggested to be a potentially useful tracer for constraining the global CH3Br budget. In order to determine the carbon isotopic composition of CH3Br emitted from the most significant anthropogenic application (pre-plant fumigation) we directly measured the δ13C of CH3Br released during commercial fumigation. We also measured the isotop...
متن کاملCarbon isotope ratios of methyl bromide and methyl chloride emitted from a coastal salt marsh
[1] Methyl bromide (CH3Br) and methyl chloride (CH3Cl) play important roles in stratospheric ozone depletion, but their atmospheric budgets have large uncertainties. The analysis of stable isotope composition of methyl halides may provide useful independent information for further constraining their budgets. Here we report the first measurements of CH3Br and CH3Cl stable carbon isotope ratios e...
