Atmospheric new particle formation from the CERN CLOUD experiment / Kirkby, Jasper (CERN) ; Amorim, António ; Baltensperger, Urs ; Carslaw, Kenneth S ; Christoudias, Theodoros ; Curtius, Joachim ; Donahue, Neil M ; Haddad, Imad El ; Flagan, Richard C ; Gordon, Hamish et al.
Aerosol particles in the atmosphere profoundly influence public health and climate. Ultrafine particles enter the body through the lungs and can translocate to essentially all organs, and they represent a major yet poorly understood health risk. [...]

Enhanced growth rate of atmospheric particles from sulfuric acid / Stolzenburg, Dominik (Vienna U. ; Helsinki U.) ; Simon, Mario (Frankfurt U.) ; Ranjithkumar, Ananth (Leeds U.) ; Kürten, Andreas (Frankfurt U.) ; Lehtipalo, Katrianne (Helsinki U. ; Finnish Meteorological Inst.) ; Gordon, Hamish (Leeds U.) ; Ehrhart, Sebastian (Mainz, Max Planck Inst.) ; Finkenzeller, Henning (U. Colorado, Boulder) ; Pichelstorfer, Lukas (Helsinki U.) ; Nieminen, Tuomo (Helsinki U.) et al.
In the present-day atmosphere, sulfuric acid is the most important vapour for aerosol particle formation and initial growth. However, the growth rates of nanoparticles ( < 10 nm) from sulfuric acid remain poorly measured. [...]

Size-dependent influence of NO$_{x}$ on the growth rates of organic aerosol particles / Yan, C (Helsinki U.) ; Nie, W (Nanjing U.) ; Vogel, A L (CERN ; PSI, Villigen) ; Dada, L (Helsinki U.) ; Lehtipalo, K (Helsinki U. ; PSI, Villigen ; Finnish Meteorological Inst.) ; Stolzenburg, D (Vienna U.) ; Wagner, R (Helsinki U.) ; Rissanen, M P (Helsinki U.) ; Xiao, M (PSI, Villigen) ; Ahonen, L (Helsinki U.) et al.
Atmospheric new-particle formation (NPF) affects climate by contributing to a large fraction of the cloud condensation nuclei (CCN). Highly oxygenated organic molecules (HOMs) drive the early particle growth and therefore substantially influence the survival of newly formed particles to CCN. [...]

Multicomponent new particle formation from sulfuric acid, ammonia, and biogenic vapors / Lehtipalo, Katrianne (U. Helsinki (main) ; PSI, Villigen ; Finnish Meteorological Inst.) ; Yan, Chao (U. Helsinki (main)) ; Dada, Lubna (U. Helsinki (main)) ; Bianchi, Federico (U. Helsinki (main)) ; Xiao, Mao (PSI, Villigen) ; Wagner, Robert (U. Helsinki (main)) ; Stolzenburg, Dominik (Vienna U.) ; Ahonen, Lauri R (U. Helsinki (main)) ; Amorim, Antonio (Lisbon, CENTRA ; Lisbon U.) ; Baccarini, Andrea (PSI, Villigen) et al.
A major fraction of atmospheric aerosol particles, which affect both air quality and climate, form from gaseous precursors in the atmosphere. Highly oxygenated organic molecules (HOMs), formed by oxidation of biogenic volatile organic compounds, are known to participate in particle formation and growth. [...]

No statistically significant effect of a short-term decrease in the nucleation rate on atmospheric aerosols / Dunne, E M (U. Leeds (main) ; Finnish Meteorological Inst.) ; Lee, L A (U. Leeds (main)) ; Reddington, C L (U. Leeds (main)) ; Carslaw, K S (U. Leeds (main))
Observed correlations between short-term decreases in cosmic ray ionisation and cloud and aerosol properties have been attributed to short-term decreases in the ion-induced nucleation rate. We use a global aerosol microphysics model to determine whether a 10 day reduction of 15% in the nucleation rate could generate a statistically significant response in aerosol concentrations and optical properties. [...]

Causes and importance of new particle formation in the present-day and preindustrial atmospheres / Gordon, Hamish (Leeds U.) ; Kirkby, Jasper (CERN ; Goethe U., Frankfurt (main)) ; Baltensperger, Urs (PSI, Villigen) ; Bianchi, Federico (Helsinki U.) ; Breitenlechner, Martin (Harvard U. (main)) ; Curtius, Joachim (Goethe U., Frankfurt (main)) ; Dias, Antonio (CERN) ; Dommen, Josef (PSI, Villigen) ; Donahue, Neil M (Carnegie Mellon U.) ; Dunne, Eimear M (Kuopio U.) et al.
New particle formation has been estimated to produce around half of cloud-forming particlesin the present-day atmosphere, via gas-to-particle conversion. Here we assess the importance of newparticle formation (NPF) for both the present-day and the preindustrial atmospheres [...]

The effect of acid–base clustering and ions on the growth of atmospheric nano-particles / Lehtipalo, Katrianne (Helsinki U. ; PSI, Villigen) ; Rondo, Linda (Frankfurt U.) ; Kontkanen, Jenni (Helsinki U.) ; Schobesberger, Siegfried (Helsinki U. ; Washington U., Seattle) ; Jokinen, Tuija (Helsinki U.) ; Sarnela, Nina (Helsinki U.) ; Kürten, Andreas (Frankfurt U.) ; Ehrhart, Sebastian (Frankfurt U. ; CERN) ; Franchin, Alessandro (Helsinki U.) ; Nieminen, Tuomo (Helsinki U.) et al.
The growth of freshly formed aerosol particles can be the bottleneck in their survival to cloud condensation nuclei. It is therefore crucial to understand how particles grow in the atmosphere. [...]

Effect of ions on sulfuric acid-water binary particle formation: 2. Experimental data and comparison with QC-normalized classical nucleation theory / Duplissy, J. ; Merikanto, J. ; Franchin, A. ; Tsagkogeorgas, G. ; Kangasluoma, J. ; Wimmer, D. ; Vuollekoski, H. ; Schobesberger, S. ; Lehtipalo, K. ; Flagan, R. C. et al.
We report comprehensive, demonstrably contaminant‐free measurements of binary particle formation rates by sulfuric acid and water for neutral and ion‐induced pathways conducted in the European Organization for Nuclear Research Cosmics Leaving Outdoor Droplets chamber. The recently developed Atmospheric Pressure interface‐time of flight‐mass spectrometer was used to detect contaminants in charged clusters and to identify runs free of any contaminants. [...]

Global atmospheric particle formation from CERN CLOUD measurements / Dunne, E M (Leeds U.) ; Gordon, H (CERN) ; Kurten, A ; Almeida, J ; Duplissy, J ; Williamson, C ; Ortega, I K ; Pringle, K J ; Adamov, A ; Baltensperger, U et al. /CLOUD
Fundamental questions remain about the origin of newly formed atmospheric aerosol particles because data from laboratory measurements have been insufficient to build global models. In contrast, gas-phase chemistry models have been based on laboratory kinetics measurements for decades. [...]
