(author), O'Dowd, C. (author), Kulmala, M. (author), Harrison, R.M. (author)The formation of new atmospheric particles involves an initial step forming stable clusters less than a nanometre in size (<~1 nm), followed by growth into quasi-stable aerosol particles a few nanometres (~1-10 nm) and larger (>~10 nm). Although at times, the same species can be responsible for both processes, it is thought that more generally...article 2018

(author), Swietlicki, E. (author), Henzing, J.S. (author)Many of the next generation of global climate models will include aerosol schemes which explicitly simulate the microphysical processes that determine the particle size distribution. These models enable aerosol optical properties and cloud condensation nuclei (CCN) concentrations to be determined by fundamental aerosol processes, which should...article 2014

(author)Clusteranalysis of particle number size distributions frombackground sites across Europeis presented. This generated a total of nine clusters of particle size distributions which could be further combined into two main groups, namely: a south-to-north category (four clusters) and a west-to-east category (five clusters). The first group was...article 2014

(author), Yttri, K.E. (author), Bergström, R. (author)The atmospheric concentration of elemental carbon (EC) in Europe during the six-year period 2005-2010 has been simulated with the EMEP MSC-W model. The model bias compared to EC measurements was less than 20% for most of the examined sites. The model results suggest that fossil fuel combustion is the dominant source of EC in most of Europe but...article 2013

Evaluation against size distribution measurements from a new European network of aerosol supersites shows that the mean model agrees...article 2013

TNO Fysisch en Elektronisch Laboratorium (author), Martensson, E.M. (author), Nilsson, E.D. (author), de Leeuw, G. (author), Cohen, L.H. (author), Hansson, H.C. (author)A major source of the primary marine aerosol is the bursting of air bubbles produced by breaking waves. Several source parameterizations are available from the literature, usually limited to particles with a dry diameter Dp > 1 um. The objective of this work is to extend the current knowledge to submicrometer particles. Bubbles were generated...article 2003
