  • Development of a combined heart-cut and comprehensive two-dimensional gas chromatography system to extend the carbon range of volatile organic compounds analysis in a single instrument 
    Dunmore, Rachel E.; Hopkins, James R.; Lidster, Richard T.; Mead, Mohammed Iqbal; Bandy, Brian J.; Forster, Grant; Oram, David E.; Sturges, William T.; Phang, Siew-Moi; Samah, Azizan Abu; Hamilton, Jacqueline F. (MDPI, 2016-07-20)
    The majority of atmospheric measurements of volatile organic compounds (VOCs) are usually limited to a small range, either in volatility or time resolution. A combined heart-cut gas chromatography (GC) with comprehensive ...
  • A growing threat to the ozone layer from short-lived anthropogenic chlorocarbons 
    Oram, David E.; Ashfold, Matthew J.; Laube, Johannes C.; Gooch, Lauren J.; Humphrey, Stephen; Sturges, William T.; Leedham-Elvidge, Emma; Forster, Grant L.; Harris, Neil R. P.; Iqbal Mead, Mohammed; Samah, Azizan Abu; Phang, Siew-Moi; Ou-Yang, Chang-Feng; Lin, Neng-Huei; Wang, Jia-Lin; Baker, Angela K.; Brenninkmeijer, Carl A. M.; Sherry, David (European Geosciences Union (EGU) / Copernicus Publications, 2017-10-12)
    Large and effective reductions in emissions of long-lived ozone-depleting substance (ODS) are being achieved through the Montreal Protocol, the effectiveness of which can be seen in the declining atmospheric abundances of ...
  • Influence of Northeast Monsoon cold surges on air quality in Southeast Asia 
    Ashfold, Matthew J.; Latif, M. T.; Samah, Azizan Abu; Mead, Mohammed Iqbal; Harris, Neil R. P. (Elsevier, 2017-07-27)
    Ozone (O3) is an important ground-level pollutant. O3 levels and emissions of O3 precursors have increased significantly over recent decades in East Asia and export of this O3 eastward across the Pacific Ocean is well ...
