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.\r\n\r\nThis dataset collection contains surface level atmospheric measurements of background ion production rates and small ion concentrations. Data from the TORCH2 campaign are also included as used by the project participants.\r\n\r\nThe Polluted Troposphere Programme was a 5-year NERC thematic research programme which was centred upon the study of polluted boundary layer air and its transport to the free troposphere. The programme focussed on the regional scale, defined as intermediate between urban and hemispheric.", "keywords": "Polluted Troposphere, Ionisation, Chemistry", "discoveryKeywords": [ 1138 ], "publicationState": "published", "dataPublishedTime": "2007-12-10T02:35:42", "doiPublishedTime": null, "member": [ "https://api.catalogue.ceda.ac.uk/api/v2/observations/1893/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/1897/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/1905/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3186/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3189/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3192/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3195/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3198/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3204/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3207/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3210/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3213/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3216/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3220/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3223/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3226/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3229/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3232/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3235/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3238/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3241/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/3247/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/14328/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/14330/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/14332/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/14334/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/14420/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observations/14423/?format=api" ], "identifier_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/identifiers/1351/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/identifiers/1352/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/identifiers/10409/?format=api" ], "responsiblepartyinfo_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/rpis/5441/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/5443/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/5444/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/5445/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/5447/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/42166/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/5442/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/42165/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/42163/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/42164/?format=api" ] }
