• Quantifying fossil fuel methane emissions using observations of atmospheric ethane and an uncertain emission ratio.

  Authors:Alice E. Ramsden, Anita L. Ganesan, Luke M. Western, Matthew Rigby, Alistair J. Manning, Amy Foulds, et al.From:Atmospheric Chemistry and Physics (Vol. 22, Issue 6) Peer-Reviewed

  Mar. 25, 2022281 words Brief article We 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...

• Swiss halocarbon emissions for 2019 to 2020 assessed from regional atmospheric observations.

  Authors:Dominique Rust, Ioannis Katharopoulos, Martin K. Vollmer, Stephan Henne, Simon O'Doherty, Daniel Say, et al.From:Atmospheric Chemistry and Physics (Vol. 22, Issue 4) Peer-Reviewed

  Feb. 23, 2022422 words Article Halocarbons 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...

• Atmospheric observations consistent with reported decline in the UK's methane emissions (2013-2020).

  Authors:Mark F. Lunt, Alistair J. Manning, Grant Allen, Tim Arnold, Stéphane J.-B. Bauguitte, Hartmut Boesch, et al.From:Atmospheric Chemistry and Physics (Vol. 21, Issue 21) Peer-Reviewed

  Nov. 5, 2021395 words Brief article 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...

• Evidence of a recent decline in UK emissions of hydrofluorocarbons determined by the InTEM inverse model and atmospheric measurements.

  Authors:Alistair J. Manning, Alison L. Redington, Daniel Say, Simon O'Doherty, Dickon Young, Peter G. Simmonds, et al.From:Atmospheric Chemistry and Physics (Vol. 21, Issue 16) Peer-Reviewed

  Aug. 27, 2021424 words Article National 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...

• Perfluorocyclobutane (PFC-318, c-C.sub.4F.sub.8) in the global atmosphere

  Authors:Cathy M. Trudinger, Luke M. Western, Matthew Rigby, Martin K. Vollmer, Sunyoung Park, Alistair J. Manning, et al.From:Atmospheric Chemistry and Physics (Vol. 19, Issue 15) Peer-Reviewed

  Aug. 14, 2019582 words Author abstract, Bri...

  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...

• Global trends and European emissions of tetrafluoromethane (CF.sub.4), hexafluoroethane (C.sub.2F.sub.6) and octafluoropropane (C.sub.3F.sub.8).

  Authors:Daniel Say, Alistair J. Manning, Luke M. Western, Dickon Young, Adam Wisher, Matthew Rigby, et al.From:Atmospheric Chemistry and Physics (Vol. 21, Issue 3) Peer-Reviewed

  Feb. 12, 2021436 words Article Perfluorocarbons (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...
