We investigated a new particle formation event in a highly polluted air mass at a regional site south of the megacity Beijing and its impact on the abundance and properties of cloud condensation nuclei (CCN). During the 1-month observation, particle nucleation followed by significant particle growth on a regional scale was observed frequently (similar to 30%), and we chose 23 August 2006 as a representative case study. Secondary aerosol mass was produced continuously, with sulfate, ammonium, and organics as major components. The aerosol mass growth rate was on average 19 mu g m(-3) h(-1) during the late hours of the day. This growth rate was observed several times during the 1-month intensive measurements. The nucleation mode grew very quickly into the size range of CCN, and the CCN size distribution was dominated by the growing nucleation mode ( up to 80% of the total CCN number concentration) and not as usual by the accumulation mode. At water vapor supersaturations of 0.07-0.86%, the CCN number concentrations reached maximum values of 4000-19,000 cm(-3) only 6-14 h after the nucleation event. During particle formation and growth, the effective hygroscopicity parameter kappa increased from about 0.1-0.3 to 0.35-0.5 for particles with diameters of 40-90 nm, but it remained nearly constant at similar to 0.45 for particles with diameters of similar to 190 nm. This result is consistent with aerosol chemical composition data, showing a pronounced increase of sulfate. 000002084 536__ $$0G:(DE-Juel1)FUEK406$$2G:(DE-HGF)$$aAtmosphäre und Klima$$cP22$$x0 000002084 588__ $$aDataset connected to Web of Science 000002084 650_7 $$2WoSType$$aJ 000002084 7001_ $$0P:(DE-HGF)0$$aCheng, Y.F.$$b1 000002084 7001_ $$0P:(DE-HGF)0$$aNowak, A.$$b2 000002084 7001_ $$0P:(DE-HGF)0$$aWehner, B.$$b3 000002084 7001_ $$0P:(DE-HGF)0$$aAchtert, P.$$b4 000002084 7001_ $$0P:(DE-HGF)0$$aBerghof, M.$$b5 000002084 7001_ $$0P:(DE-HGF)0$$aBirmili, Z.$$b6 000002084 7001_ $$0P:(DE-HGF)0$$aWu, J.$$b7 000002084 7001_ $$0P:(DE-HGF)0$$aHu, M.$$b8 000002084 7001_ $$0P:(DE-HGF)0$$aZhu, T.$$b9 000002084 7001_ $$0P:(DE-HGF)0$$aTakegawa, N.$$b10 000002084 7001_ $$0P:(DE-HGF)0$$aKita, K.$$b11 000002084 7001_ $$0P:(DE-HGF)0$$aKondo, Y.$$b12 000002084 7001_ $$0P:(DE-Juel1)VDB81049$$aLou, S.R.$$b13$$uFZJ 000002084 7001_ $$0P:(DE-Juel1)16326$$aHofzumahaus, A.$$b14$$uFZJ 000002084 7001_ $$0P:(DE-Juel1)16342$$aHolland, F.$$b15$$uFZJ 000002084 7001_ $$0P:(DE-Juel1)16324$$aWahner, A.$$b16$$uFZJ 000002084 7001_ $$0P:(DE-HGF)0$$aGunthe, S.S.$$b17 000002084 7001_ $$0P:(DE-HGF)0$$aRose, D.$$b18 000002084 7001_ $$0P:(DE-HGF)0$$aSu, H.$$b19 000002084 7001_ $$0P:(DE-HGF)0$$aPöschl, U.$$b20 000002084 773__ $$0PERI:(DE-600)2016800-7$$a10.1029/2008JD010884$$gVol. 114, p. 1 - 13$$p1 - 13$$q114<1 - 13$$tJournal of geophysical research / Atmospheres$$tJournal of Geophysical Research$$v114$$x0148-0227$$y2009 000002084 8567_ $$uhttp://dx.doi.org/10.1029/2008JD010884 000002084 8564_ $$uhttps://juser.fz-juelich.de/record/2084/files/2008JD010884.pdf$$yOpenAccess 000002084 8564_ $$uhttps://juser.fz-juelich.de/record/2084/files/2008JD010884.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000002084 909CO $$ooai:juser.fz-juelich.de:2084$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000002084 9141_ $$y2009 000002084 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000002084 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR 000002084 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000002084 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000002084 915__ $$0StatID:(DE-HGF)0010$$2StatID$$aJCR/ISI refereed 000002084 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer review 000002084 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000002084 9131_ $$0G:(DE-Juel1)FUEK406$$aDE-HGF$$bUmwelt$$kP22$$lAtmosphäre und Klima$$vAtmosphäre und Klima$$x0$$zfortgesetzt als P23 000002084 9201_ $$0I:(DE-Juel1)VDB791$$d30.09.2010$$gICG$$kICG-2$$lTroposphäre$$x1 000002084 970__ $$aVDB:(DE-Juel1)104505 000002084 9801_ $$aFullTexts 000002084 980__ $$aVDB 000002084 980__ $$aConvertedRecord 000002084 980__ $$ajournal 000002084 980__ $$aI:(DE-Juel1)IEK-8-20101013 000002084 980__ $$aUNRESTRICTED 000002084 981__ $$aI:(DE-Juel1)ICE-3-20101013 000002084 981__ $$aI:(DE-Juel1)IEK-8-20101013
