  • CH4 emission estimates from an active landfill site inferred from a combined approach of CFD modelling and in situ FTIR measurements 
    Sonderfeld, Hannah; Bösch, Hartmut; Jeanjean, Antoine P. R.; Riddick, Stuart N.; Grant, Allen; Ars, Sébastien; Davies, Stewart; Harris, Neil R. P.; Humpage, Neil; Leigh, Roland; Pitt, Joseph (European Geosciences Union / Copernicus Publications, 2017-04-03)
    Globally, the waste sector contributes to nearly a fifth of anthropogenic methane emitted to the atmosphere and is the second largest source of methane in the UK. In recent years great improvements to reduce those emissions ...
  • Development of a low-maintenance measurement approach to continuously estimate methane emissions: a case study 
    Riddick, Stuart N.; Hancock, B. R.; Robinson, Andrew D.; Connors, Sarah; Davies, S.; Allen, Grant; Pitt, Joseph; Harris, Neil R. P. (Elsevier, 2016-12-18)
    The chemical breakdown of organic matter in landfills represents a significant source of methane gas (CH4). Current estimates suggest that landfills are responsible for between 3% and 19% of global anthropogenic emissions. ...
  • Estimating the size of a methane emission point source at different scales: from local to landscape 
    Riddick, Stuart N.; Connors, Sarah; Robinson, Andrew D.; Manning, Alistair J.; Jones, Pippa S. D.; Lowry, David; Nisbet, Euan; Skelton, Robert L.; Allen, Grant; Pitt, Joseph; Harris, Neil R. P. (European Geosciences Union (EGU) / Copernicus Publications, 2017-06-29)
    High methane (CH4) mixing ratios (up to 4 ppm) have occurred sporadically at our measurement site in Haddenham, Cambridgeshire, since July 2012. Isotopic measurements and back trajectories show that the source is the ...
  • Estimating the size of a methane emission point-source at different scales: from local to landscape 
    Riddick, Stuart N.; Connors, Sarah; Robinson, Andrew D.; Manning, Alistair J.; Jones, Pippa S. D.; Lowry, David; Nisbet, Euan; Skelton, Robert L.; Allen, Grant; Pitt, Joseph; Harris, Neil R. P. (Copernicus Publications, 2016-11-22)
    High methane (CH4) mixing ratios (up to 4 ppm) have occurred sporadically at our measurement site in Haddenham, Cambridgeshire since July 2012. Isotopic measurements and back trajectories show that the source is the ...
  • A measurement-based verification framework for UK greenhouse gas emissions: an overview of the Greenhouse gAs Uk and Global Emissions (GAUGE) project 
    Palmer, Paul I.; O'Doherty, Simon; Allen, Grant; Bower, Keith; Bösch, Hartmut; Chipperfield, Martyn P.; Connors, Sarah; Dhomse, Sandip; Feng, Liang; Finch, Douglas P.; Gallagher, Martin W.; Gloor, Emanuel; Gonzi, Siegfried; Harris, Neil R. P.; Helfter, Carole; Humpage, Neil; Kerridge, Brian; Knappett, Diane; Jones, Roderic L.; Le Breton, Michael; Lunt, Mark F.; Manning, Alistair J.; Matthiesen, Stephan; Muller, Jennifer B. A.; Mullinger, Neil; Nemitz, Eiko; O'Shea, Sebastian; Parker, Robert J.; Percival, Carl J.; Pitt, Joseph; Riddick, Stuart N.; Rigby, Matthew; Sembhi, Harjinder; Siddans, Richard; Skelton, Robert L.; Smith, Paul; Sonderfeld, Hannah; Stanley, Kieran; Stavert, Ann R.; Wenger, Angelina; White, Emily; Wilson, Christopher; Young, Dickon (Elsevier, 2018-08-17)
    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, distribution, ...
  • Measuring methane emissions from oil and gas platforms in the North Sea 
    Riddick, Stuart N.; Mauzerall, Denise L.; Celia, Michael; Harris, Neil R. P.; Allen, Grant; Pitt, Joseph; Staunton-Sykes, John; Forster, Grant L.; Kang, Mary; Lowry, David; Nisbet, Euan; Manning, Alistair J. (European Geosciences Union (EGU) / Copernicus Publications, 2019-08-02)
    Since 1850 the concentration of atmospheric methane (CH4), a potent greenhouse gas, has more than doubled. Recent studies suggest that emission inventories may be missing sources and underestimating emissions. To investigate ...
