New particle formation from isoprene under upper-tropospheric conditions / Shen, Jiali (Helsinki U.) ; Russell, Douglas M (Frankfurt U., FIAS) ; DeVivo, Jenna (Carnegie Mellon U.) ; Kunkler, Felix (Mainz, Max Planck Inst.) ; Baalbaki, Rima (Helsinki U.) ; Mentler, Bernhard (Innsbruck U.) ; Scholz, Wiebke (Innsbruck U.) ; Yu, Wenjuan (Helsinki U.) ; Caudillo-Plath, Lucía (Frankfurt U., FIAS) ; Sommer, Eva (CERN ; Vienna U.) et al.
Abstract Aircraft observations have revealed ubiquitous new particle formation in the tropical upper troposphere over the Amazon1,2 and the Atlantic and Pacific oceans3,4. Although the vapours involved remain unknown, recent satellite observations have revealed surprisingly high night-time isoprene mixing ratios of up to 1 part per billion by volume (ppbv) in the tropical upper troposphere5.

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. [...]

Formation of Highly Oxygenated Organic Molecules from $\alpha$-Pinene Ozonolysis: Chemical Characteristics, Mechanism, and Kinetic Model Development / Molteni, Ugo (PSI, Villigen) ; Simon, Mario (Frankfurt U.) ; Heinritzi, Martin (Frankfurt U.) ; Hoyle, Christopher R (PSI, Villigen) ; Bernhammer, Anne-Kathrin (Ionicon GesmbH, Innsbruck) ; Bianchi, Federico (Helsinki U.) ; Breitenlechner, Martin (Innsbruck U.) ; Brilke, Sophia (Frankfurt U.) ; Dias, António (Lisbon U.) ; Duplissy, Jonathan (Helsinki U. ; Helsinki Inst. of Phys.) et al.
Terpenes are emitted by vegetation, and their oxidation in the atmosphere is an important source of secondary organic aerosol (SOA). A part of this oxidation can proceed through an autoxidation process, yielding highly oxygenated organic molecules (HOMs) with low saturation vapor pressure. [...]

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. [...]

Molecular understanding of new-particle formation from $\alpha$-pinene between −50 and +25 °C / Simon, Mario (Frankfurt U.) ; Dada, Lubna (Helsinki U.) ; Heinritzi, Martin (Frankfurt U.) ; Scholz, Wiebke (Innsbruck U.) ; Stolzenburg, Dominik (Vienna U.) ; Fischer, Lukas (Innsbruck U.) ; Wagner, Andrea C (Frankfurt U. ; U. Colorado, Boulder) ; Kürten, Andreas (Frankfurt U.) ; Rörup, Birte (Helsinki U.) ; He, Xu-Cheng (Helsinki U.) et al.
Highly oxygenated organic molecules (HOMs) contribute substantially to the formation and growth of atmospheric aerosol particles, which affect air quality, human health and Earth’s climate. HOMs are formed by rapid, gasphase autoxidation of volatile organic compounds (VOCs) such as α-pinene, the most abundant monoterpene in the atmosphere. [...]

Molecular understanding of the suppression of new-particle formation by isoprene / Heinritzi, Martin (Frankfurt U.) ; Dada, Lubna (Helsinki U.) ; Simon, Mario (Frankfurt U.) ; Stolzenburg, Dominik (Vienna U.) ; Wagner, Andrea C (Frankfurt U. ; U.

Nucleation of atmospheric vapours produces more than half of global cloud condensation nuclei and so has an important influence on climate. Recent studies show that monoterpene (C$_{10}$H$_{16}$) oxidation yields highly oxygenated products that can nucleate with or without sulfuric acid. [...]

Rapid growth of organic aerosol nanoparticles over a wide tropospheric temperature range / Stolzenburg, Dominik (Vienna U.) ; Fischer, Lukas (Innsbruck U.) ; Vogel, Alexander L (Frankfurt U. ; CERN ; PSI, Villigen) ; Heinritzi, Martin (Frankfurt U.) ; Schervish, Meredith (Carnegie Mellon U.) ; Simon, Mario (Frankfurt U.) ; Wagner, Andrea C (Frankfurt U.) ; Dada, Lubna (Helsinki U.) ; Ahonen, Lauri R (Helsinki U.) ; Amorim, Antonio (Lisbon U. ; CMAF, Lisbon) et al.
Nucleation and growth of aerosol particles from atmospheric vapors constitutes a major source of global cloud condensation nuclei (CCN). The fraction of newly formed particles that reaches CCN sizes is highly sensitive to particle growth rates, especially for particle sizes <10 nm, where coagulation losses to larger aerosol particles are greatest.
