This network reaches from the Azores to the Hungarian plain to represent marine, coastal, mountain and continental conditions. The motivation for observing this natural secondary aerosol tracer was to give insight to what extent it might assist in understanding the more complex aerosol chemistry changes. Synopsis of the <jats:sup>210<\/jats:sup>Pb variability revealed a continental increase, up to a factor of three, from west to east. During the three winter months, we find a variation on nearly the same order in the <jats:sup>210<\/jats:sup>Pb concentration between low\u2010 and high\u2010altitude sites. Seasonal <jats:sup>210<\/jats:sup>Pb cycles exhibit summer\/winter ratios of around 2\u20133 at high\u2010altitude sites, but remain damped at low\u2010altitude stations. However, all sites show distinct <jats:sup>210<\/jats:sup>Pb changes of around \u00b150% independent of season on the synoptic timescale. Comparison of concentration variations of organic carbon (OC) and anthropogenic sulphate with the <jats:sup>210<\/jats:sup>Pb variations show largest differences associated with the seasonal cycle at the low\u2010altitude sites. In contrast, significant covariations of all three components are seen on the synoptic timescale for these sites. At high altitudes, clear covariations of OC and anthropogenic sulphate with <jats:sup>210<\/jats:sup>Pb are seen on both seasonal and synoptic timescales. At two mountain sites with comparable elevation, all three aerosol compounds show strong intersite correlations along with systematic enhancements at the downwind site. Attributing these offsets to a common continental pileup, simple 1\u2010box model calculations yielded OC\u2010 and anthropogenic sulphate\u2010related emission flux densities, which are broadly in agreement with the expected values.<\/jats:p>","DOI":"10.1029\/2006jd008065","type":"journal-article","created":{"date-parts":[[2007,9,24]],"date-time":"2007-09-24T20:01:09Z","timestamp":1190664069000},"source":"Crossref","is-referenced-by-count":17,"title":["Lead\u2010210 observations within CARBOSOL: A diagnostic tool for assessing the spatiotemporal variability of related chemical aerosol species?"],"prefix":"10.1029","volume":"112","author":[{"given":"S.","family":"Hammer","sequence":"first","affiliation":[{"name":"Institut f\u00fcr Umweltphysik University of Heidelberg  Heidelberg Germany"}]},{"given":"D.","family":"Wagenbach","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Umweltphysik University of Heidelberg  Heidelberg Germany"}]},{"given":"S.","family":"Preunkert","sequence":"additional","affiliation":[{"name":"Laboratoire de Glaciologie et G\u00e9ophysique de l'Environnement Centre National de la Recherche Scientifique  St. Martin d'H\u00e8res France"}]},{"given":"C.","family":"Pio","sequence":"additional","affiliation":[{"name":"Centre for Environmental and Marine Studies and Department of Environment University of Aveiro  Aveiro Portugal"}]},{"given":"C.","family":"Schlosser","sequence":"additional","affiliation":[{"name":"Federal Office for Radiation Protection  Freiburg Germany"}]},{"given":"F.","family":"Meinhardt","sequence":"additional","affiliation":[{"name":"Umweltbundesamt, Messstelle Schauinsland  Kirchzarten Germany"}]}],"member":"13","published-online":{"date-parts":[[2007,9,25]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1029\/2004JD004939"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.5194\/acp-5-3389-2005"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1029\/2003JD003751"},{"key":"e_1_2_8_5_1","doi-asserted-by":"crossref","first-page":"54","DOI":"10.1579\/0044-7447-34.1.54","article-title":"The contribution from shipping emissions to air quality and acid deposition in Europe","volume":"34","author":"Derwent R.
