From:Atmospheric Chemistry and Physics (Vol. 22, Issue 9) Peer-ReviewedThe emissions of hydrofluorocarbons (HFCs) have increased significantly in the past 2 decades, primarily as a result of the phaseout of ozone-depleting substances under the Montreal Protocol and the use of HFCs as their...

From:Atmospheric Chemistry and Physics (Vol. 22, Issue 8) Peer-ReviewedMethyl bromide (CH.sub.3 Br) is a potent ozone-depleting substance (ODS) that has both natural and anthropogenic sources. CH.sub.3 Br has been used mainly for preplant soil fumigation, post-harvest grain and timber...

From:Atmospheric Chemistry and Physics (Vol. 22, Issue 6) Peer-ReviewedWe present a method for estimating fossil fuel methane emissions using observations of methane and ethane, accounting for uncertainty in their emission ratio. The ethane:methane emission ratio is incorporated as a...

From:Atmospheric Chemistry and Physics (Vol. 22, Issue 5) Peer-ReviewedEmissions of the potent greenhouse gas perfluorocyclobutane (c-C.sub.4 F.sub.8, PFC-318, octafluorocyclobutane) into the global atmosphere inferred from atmospheric measurements have been increasing sharply since the...

From:Atmospheric Chemistry and Physics (Vol. 22, Issue 4) Peer-ReviewedHalocarbons contribute to global warming and stratospheric ozone depletion. They are emitted to the atmosphere by various anthropogenic activities. To determine Swiss national halocarbon emissions, we applied top-down...

From:Atmospheric Chemistry and Physics (Vol. 21, Issue 16) Peer-ReviewedNational greenhouse gas inventories (GHGIs) are submitted annually to the United Nations Framework Convention on Climate Change (UNFCCC). They are estimated in compliance with Intergovernmental Panel on Climate Change...

From:Atmospheric Measurement Techniques (Vol. 14, Issue 8) Peer-ReviewedThe precise measurement of the amount fraction of atmospheric nitrous oxide (N.sub.2 O) is required to understand global emission trends. Analysis of the site-specific stable isotopic composition of N.sub.2 O provides a...

From:Atmospheric Chemistry and Physics (Vol. 17, Issue 18) Peer-ReviewedFollowing the recent Global Carbon Project (GCP) synthesis of the decadal methane (CH.sub.4) budget over 2000-2012 (Saunois et al., 2016), we analyse here the same dataset with a focus on quasi-decadal and inter-annual...

From:Atmospheric Chemistry and Physics (Vol. 19, Issue 15) Peer-Reviewed
We reconstruct atmospheric abundances of the potent greenhouse gas c-C.sub.4 F.sub.8 (perfluorocyclobutane, perfluorocarbon PFC-318) from measurements of in situ, archived, firn, and aircraft air samples with...

From:Atmospheric Chemistry and Physics (Vol. 20, Issue 12) Peer-ReviewedThe Arctic is one of the most rapidly warming regions of the Earth, with predicted temperature increases of 5-7 .sup." C and the accompanying extensive retreat of Arctic glacial systems by 2100. Retreating...

From:Atmospheric Chemistry and Physics (Vol. 19, Issue 22) Peer-ReviewedWe present Î.sup.14 CO.sub.2 observations and related greenhouse gas measurements at a background site in Ireland (Mace Head, MHD) and a tall tower site in the east of the UK (Tacolneston, TAC) that is more strongly...

From:Earth System Science Data (Vol. 12, Issue 3) Peer-ReviewedUnderstanding and quantifying the global methane (CH.sub.4) budget is important for assessing realistic pathways to mitigate climate change. Atmospheric emissions and concentrations of CH.sub.4 continue to increase,...

From:Atmospheric Chemistry and Physics (Vol. 18, Issue 16) Peer-Reviewed
We describe the motivation, design, and execution of the Greenhouse gAs Uk and Global Emissions (GAUGE) project. The overarching scientific objective of GAUGE was to use atmospheric data to estimate the magnitude,...

From:Atmospheric Chemistry and Physics (Vol. 20, Issue 12) Peer-ReviewedWe report a 40-year history of SF.sub.6 atmospheric mole fractions measured at the Advanced Global Atmospheric Gases Experiment (AGAGE) monitoring sites, combined with archived air samples, to determine emission...

From:Atmospheric Chemistry and Physics (Vol. 20, Issue 21) Peer-ReviewedBrazil's CH.sub.4 emissions over the period 2010-2018 were derived for the three main sectors of activity: anthropogenic, wetland and biomass burning. Our inverse modelling estimates were derived from GOSAT (Greenhouse...
