Journal ArticleDOI
Methane emissions from terrestrial plants under aerobic conditions
TL;DR: It is demonstrated using stable carbon isotopes that methane is readily formed in situ in terrestrial plants under oxic conditions by a hitherto unrecognized process, suggesting that this newly identified source may have important implications for the global methane budget and may call for a reconsideration of the role of natural methane sources in past climate change.
Journal ArticleDOI
Methoxyl groups of plant pectin as a precursor of atmospheric methane: evidence from deuterium labelling studies.
TL;DR: Results clearly demonstrate that ester methyl groups of pectin can serve as a precursor ofCH4, supporting the idea of a novel chemical route of CH4 formation in plants under oxic environmental conditions.
Journal ArticleDOI
Isotopic composition of H2 from CH4 oxidation in the stratosphere and the troposphere
TL;DR: In this article, a Rayleigh model was used to account for the isotopic fractionations in the photochemical chain reactions from CH4 to the final product H2O via H2 reveals a strong enrichment of photochemically produced H2.
Journal ArticleDOI
Fractional release factors of long-lived halogenated organic compounds in the tropical stratosphere
Johannes C. Laube,Johannes C. Laube,Andreas Engel,Harald Bönisch,T. Möbius,William T. Sturges,Marc Braß,Thomas Röckmann +7 more
TL;DR: In this paper, the first set of vertically resolved fractional release factors for 15 long-lived halocarbons in the tropical stratosphere up to 34 km altitude were calculated from measurements on air samples collected on board balloons and a high altitude aircraft.
