TL;DR: A review of the state of scientific understanding in relation to global and regional air quality is outlined in this article, in terms of emissions, processing and transport of trace gases and aerosols.
Journal ArticleDOI

TL;DR: In this paper, the formation of new particles in a smog chamber simulating the photochemical formation of H2SO4 and organic condensable species was investigated, and the measured particle formation rates were proportional to the product of the concentrations of H 2 SO4 and an organic molecule.
Journal ArticleDOI
On the roles of sulphuric acid and low-volatility organic vapours in the initial steps of atmospheric new particle formation
Pauli Paasonen,Tuomo Nieminen,Eija Asmi,Hanna E. Manninen,Tuukka Petäjä,C. Plass-Dülmer,H. Flentje,Wolfram Birmili,A. Wiedensohler,Urmas Hõrrak,A. Metzger,A. Hamed,Ari Laaksonen,Maria Cristina Facchini,V.-M. Kerminen,Markku Kulmala,Markku Kulmala +16 more
TL;DR: In this article, the authors analyzed 36 new particle formation events observed at four European measurement sites during EUCAARI campaigns in 2007-2009 and determined the related nucleation coefficients connecting the neutral nucleation rate J with the vapour concentrations in each mechanism.
Journal ArticleDOI
Laboratory observation of oligomers in the aerosol from isoprene/NOx photooxidation
J. Dommen,A. Metzger,Jonathan Duplissy,Markus Kalberer,M. R. Alfarra,A. Gascho,Ernest Weingartner,André S. H. Prévôt,Bart Verheggen,Urs Baltensperger +9 more
TL;DR: In this article, a matrix assisted laser desorption/ionization mass spectrometry was used to detect the formation of high molecular weight compounds over the course of 15-hour experiments.
