Size Matters More Than Chemistry for Cloud-Nucleating Ability of Aerosol Particles
Ulrike Dusek,Göran Frank,Lea Hildebrandt,Lea Hildebrandt,Joachim Curtius,Johannes Schneider,S. Walter,Duli Chand,Frank Drewnick,Silke S. Hings,D Jung,Stephan Borrmann,Meinrat O. Andreae +12 more
TL;DR: Size-resolved cloud condensation nuclei spectra measured for various aerosol types at a non-urban site in Germany showed that CCN concentrations are mainly determined by the aerosol number size distribution.
Journal ArticleDOI
Organic aerosol components observed in Northern Hemispheric datasets from Aerosol Mass Spectrometry

TL;DR: In this article, the authors present results from the factor analysis of 43 AMS datasets (27 of the datasets are reanalyzed in this work) and provide a holistic overview of Northern Hemisphere organic aerosol (OA) and its evolution in the atmosphere.
Journal ArticleDOI
Chemical composition of secondary organic aerosol formed from the photooxidation of isoprene
Jason D. Surratt,Shane M. Murphy,Jesse H. Kroll,Nga L. Ng,Lea Hildebrandt,Armin Sorooshian,Rafal Szmigielski,Reinhilde Vermeylen,Willy Maenhaut,Magda Claeys,Richard C. Flagan,John H. Seinfeld +11 more
TL;DR: The first evidence of particle-phase esterification reactions in SOA, where the further oxidation of the isoprene oxidation product methacrolein under high-NO(x) conditions produces polyesters involving 2-methylglyceric acid as a key monomeric unit.
Journal ArticleDOI
High formation of secondary organic aerosol from the photo-oxidation of toluene
TL;DR: In this article, an approximate parameterization is proposed for use in air quality models until a more thorough treatment accounting for the dynamic nature of the photochemical aging of the toluene SOA.
Journal ArticleDOI
Ubiquity of organic nitrates from nighttime chemistry in the European submicron aerosol

TL;DR: In this article, particle phase measurements performed at a suburban site in the Netherlands showed that organic nitrates contribute substantially to particulate nitrate and organic mass, implying a substantial potential of PM reduction by NOx emission control.
