Insight into Acid–Base Nucleation Experiments by Comparison of the Chemical Composition of Positive, Negative, and Neutral Clusters / Bianchi, Federico (PSI, Villigen) ; Praplan, Arnaud P (Helsinki U.) ; Sarnela, Nina (Helsinki U.) ; Dommen, Josef (PSI, Villigen) ; Kürten, Andreas (Goethe U., Frankfurt (main)) ; Ortega, Ismael K (Lille U.) ; Schobesberger, Siegfried (Helsinki U.) ; Junninen, Heikki (Helsinki U.) ; Simon, Mario (Goethe U., Frankfurt (main)) ; Tröstl, Jasmin (PSI, Villigen) et al.
We investigated the nucleation of sulfuric acid together with two bases (ammonia and dimethylamine), at the CLOUD chamber at CERN. The chemical composition of positive, negative, and neutral clusters was studied using three Atmospheric Pressure interface-Time Of Flight (APi-TOF) mass spectrometers: two were operated in positive and negative mode to detect the chamber ions, while the third was equipped with a nitrate ion chemical ionization source allowing detection of neutral clusters.

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. [...]

The role of low-volatility organic compounds in initial particle growth in the atmosphere / Tröstl, Jasmin (PSI, Villigen) ; Chuang, Wayne K (Carnegie Mellon U. (main)) ; Gordon, Hamish (CERN) ; Heinritzi, Martin (Goethe U., Frankfurt (main)) ; Yan, Chao (Helsinki U.) ; Molteni, Ugo (PSI, Villigen) ; Ahlm, Lars (Stockholm U. (main)) ; Frege, Carla (PSI, Villigen) ; Bianchi, Federico (PSI, Villigen ; Helsinki U. ; ETH, Zurich (main)) ; Wagner, Robert (Helsinki U.) et al.
About half of present-day cloud condensation nuclei originate from atmospheric nucleation, frequently appearing as a burst of new particles near midday. Atmospheric observations show that the growth rate of new particles often accelerates when the diameter of the particles is between one and ten nanometres. [...]

Ion-induced nucleation of pure biogenic particles / Kirkby, Jasper (Goethe U., Frankfurt (main) ; CERN) ; Duplissy, Jonathan (Helsinki U. ; Helsinki Inst. of Phys.) ; Sengupta, Kamalika (U. Leeds (main)) ; Frege, Carla (PSI, Villigen) ; Gordon, Hamish (CERN) ; Williamson, Christina (Goethe U., Frankfurt (main)) ; Heinritzi, Martin (Goethe U., Frankfurt (main) ; Innsbruck U.) ; Simon, Mario (Goethe U., Frankfurt (main)) ; Yan, Chao (Helsinki U.) ; Almeida, João (Goethe U., Frankfurt (main) ; CERN) et al.
Atmospheric aerosols and their effect on clouds are thought to be important for anthropogenic radiative forcing of the climate, yet remain poorly understood. Globally, around half of cloud condensation nuclei originate from nucleation of atmospheric vapours. [...]

Neutral molecular cluster formation of sulfuric acid–dimethylamine observed in real time under atmospheric conditions / Kürten, Andreas (Goethe U., Frankfurt (main)) ; Jokinen, Tuija (Helsinki U.) ; Simon, Mario (Goethe U., Frankfurt (main)) ; Sipilä, Mikko (Helsinki U. ; Helsinki Inst. of Phys.) ; Sarnela, Nina (Helsinki U.) ; Junninen, Heikki (Helsinki U.) ; Adamov, Alexey (Helsinki U.) ; Almeida, João (Goethe U., Frankfurt (main) ; CERN) ; Amorim, Antonio (UBI, Covilha ; U. Lisbon (main)) ; Bianchi, Federico (PSI, Villigen) et al.
For atmospheric sulfuric acid (SA) concentrations the presence of dimethylamine (DMA) at mixing ratios of several parts per trillion by volume can explain observed boundary layer new particle formation rates. However, the concentration and molecular composition of the neutral (uncharged) clusters have not been reported so far due to the lack of suitable instrumentation. [...]

Molecular understanding of sulphuric acid-amine particle nucleation in the atmosphere / Almeida, João (Goethe U., Frankfurt ; CERN) ; Schobesberger, Siegfried (Helsinki U.) ; Kürten, Andreas (Goethe U., Frankfurt) ; Ortega, Ismael K (Helsinki U.) ; Kupiainen-Määttä, Oona (Helsinki U.) ; Praplan, Arnaud P (PSI, Villigen) ; Adamov, Alexey (Helsinki U.) ; Amorim, Antonio (U. Lisbon ; U. Beira Int., Lisbon) ; Bianchi, Federico (PSI, Villigen) ; Breitenlechner, Martin (U. Innsbruck) et al.
Nucleation of aerosol particles from trace atmospheric vapours is thought to provide up to half of global cloud condensation nuclei. Aerosols can cause a net cooling of climate by scattering sunlight and by leading to smaller but more numerous cloud droplets, which makes clouds brighter and extends their lifetimes. [...]
