    • Influence of temperature on the molecular composition of ions and charged clusters during pure biogenic nucleation 

      Frege, Carla; Ortega, Ismael K; Rissanen, Matti P; Praplan, Arnaud P; Steiner, Gerhard; Heinritzi, Martin; Ahonen, Lauri; Amorim, António; Bernhammer, Anne-Kathrin; Bianchi, Federico; Brilke, Sophia; Breitenlechner, Martin; Dada, Lubna; Dias, António; Duplissy, Jonathan; Ehrhart, Sebastian; El-Haddad, Imad; Fischer, Lukas; Fuchs, Claudia; Garmash, Olga et al [incl Schobesberger Siegfried] (Copernicus GmbHSaksa, 2018)
      It was recently shown by the CERN CLOUD experiment that biogenic highly oxygenated molecules (HOMs) form particles under atmospheric conditions in the absence of sulfuric acid, where ions enhance the nucleation rate by 1–2 ...
    • The role of H2SO4-NH3 anion clusters in ion-induced aerosol nucleation mechanisms in the boreal forest 

      Yan, Chao; Dada, Lubna; Rose, Clemence; Jokinen, Tuija; Nie, Wei; Schobesberger, Siegfried; Junninen, Heikki; Lehtipalo, Katrianne; Sarnela, Nina; Makkonen, Ulla; Garmash, Olga; Wang, Yonghong; Zha, Qiaozhi; Paasonen, Pauli; Bianchi, Federico; Sipilä, Mikko; Ehn, Mikael; Petäjä, Tuukka; Kerminen, Veli-Matti; Worsnop, Douglas R; Kulmala, Markku (Copernicus GmbHSaksa, 2018)
      New particle formation (NPF) provides a large source of atmospheric aerosols, which affect the climate and human health. In recent chamber studies, ion-induced nucleation (IIN) has been discovered as an important pathway ...
