Atmospheric Cluster Dynamics Code: a flexible method for solution of the birth-death equations
Matthew J. McGrath,Matthew J. McGrath,Tinja Olenius,Ismael K. Ortega,Ville Loukonen,Pauli Paasonen,Theo Kurtén,Markku Kulmala,Hanna Vehkamäki +8 more
TL;DR: The Atmospheric Cluster Dynamics Code (ACDC) as mentioned in this paper was created to study the first steps of atmospheric new particle formation by examining the formation of molecular clusters from atmospherically relevant molecules.
Journal ArticleDOI
Rapid Autoxidation Forms Highly Oxidized RO2 Radicals in the Atmosphere
Tuija Jokinen,Tuija Jokinen,Mikko Sipilä,Stefanie Richters,Veli-Matti Kerminen,Pauli Paasonen,Frank Stratmann,Douglas R. Worsnop,Markku Kulmala,Mikael Ehn,Hartmut Herrmann,Torsten Berndt +11 more
TL;DR: The well-known reaction principle of autoxidation is also applicable to the atmospheric gas-phase oxidation of hydrocarbons leading to extremely low-volatility products which contribute to organic aerosol mass and hence influence the aerosol-cloud-climate system.
Journal ArticleDOI
Dispersion of particles and trace gases nearby a city highway: Mobile laboratory measurements in Finland

TL;DR: In this paper, a mobile laboratory at a major highway and in its vicinity, 0-140m from the road side, in Helsinki, during the summer and winter campaigns in 2003 and 2004.

TL;DR: The results obtained during the EUCAARI project indicate that sulphuric acid plays a central role in atmospheric nucleation as discussed by the authors, but also vapours other than sulphurica are needed to explain the nucleation and the subsequent growth processes.

On the formation of sulphuric acid - amine clusters in varying atmospheric conditions and its influence on atmospheric new particle formation
Pauli Paasonen,Pauli Paasonen,Tinja Olenius,Oona Kupiainen,Theo Kurtén,Tuukka Petäjä,Wolfram Birmili,A. Hamed,Min Hu,L. G. Huey,C. Plass-Duelmer,James N. Smith,James N. Smith,A.

TL;DR: In this article, the formation rate of clusters with two sulphuric acid and two amine molecules (JA2B2) was modelled at varying atmospherically relevant conditions with respect to concentrations of sulfate acid ([H2SO4]), dimethylamine ([DMA]) and trimethyamine ([TMA]), temperature and relative humidity (RH).
