A synthesis of cloud condensation nuclei counter (CCNC) measurements within the EUCAARI network
(2015)Atmospheric Chemistry and PhysicsCloud condensation nuclei counter (CCNC) measurements performed at 14 locations around the world within the European Integrated project on Aerosol Cloud Climate and Air Quality interactions (EUCAARI) framework have been analysed and discussed with respect to the cloud condensation nuclei (CCN) activation and hygroscopic properties of the atmospheric aerosol. The annual mean ratio of activated cloud condensation nuclei (NCCN) to the total ...Journal Article -
Variations in tropospheric submicron particle size distributions across the European continent 2008-2009
(2014)Atmospheric Chemistry and PhysicsCluster~analysis of particle number size distributions from~background sites across Europe~is 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 identified as most frequently being detected inside and around northern Germany and neighbouring ...Journal Article -
Primary versus secondary contributions to particle number concentrations in the European boundary layer
(2011)Atmospheric Chemistry and PhysicsIt is important to understand the relative contribution of primary and secondary particles to regional and global aerosol so that models can attribute aerosol radiative forcing to different sources. In large-scale models, there is considerable uncertainty associated with treatments of particle formation (nucleation) in the boundary layer (BL) and in the size distribution of emitted primary particles, leading to uncertainties in predicted ...Journal Article
