- Abstract:
- Formation of ultrafine particles from molecular cluster ions in the atmosphere has recently been 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 is sensitive to gas composition and condensable vapour supply. The work will measure 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.
