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...

Atmospheric observations consistent with reported decline in the UK's methane emissions (2013-2020).
Atmospheric measurements can be used as a tool to evaluate national greenhouse gas inventories through inverse modelling. Using 8 years of continuous methane (CH.sub.4) concentration data, this work assesses the United... -
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...

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. 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:Geoscientific Model Development (Vol. 13, Issue 4) Peer-ReviewedWe present a method to infer spatially and spatio-temporally correlated emissions of greenhouse gases from atmospheric measurements and a chemical transport model. The method allows fast computation of spatial emissions...

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...

From:Atmospheric Chemistry and Physics (Vol. 21, Issue 3) Peer-ReviewedPerfluorocarbons (PFCs) are amongst the most potent greenhouse gases listed under the United Nations Framework Convention on Climate Change (UNFCCC). With atmospheric lifetimes on the order of thousands to tens of...
