    "title": "Polluted Troposphere Ionisation as a Precursor to Aerosol Formation project",
    "abstract": "Ionisation as a precursor to aerosol formation was a NERC Polluted Troposphere Research Programme project (Round 1 - NER/T/S/2002/00150 - Duration 2002 - 2005) and was led by Dr RG Harrison, University of Reading.\r\n\r\nFormation of ultrafine particles from molecular cluster ions in the atmosphere has recently shown to occur in urban air, from both experimental findings and theoretical considerations. Ion-induced (or mediated) aerosol formation is currently neglected, despite the considerable variability known in atmospheric ions. Ionisation in the atmosphere is ubiquitous, arising from cosmic rays and natural radioactivity, with a further contribution from nuclear reprocessing. The efficiency of ion to particle conversion was sensitive to gas composition and condensable vapour supply. \r\n\r\nThe work measured ion-induced ultrafine particle production in surface air, combining ion and aerosol data. Existing ion-aerosol theory will be extended to include particle production from ions, to assess the significance for clouds of additional condensation nuclei.",
