/ 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.

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. [...]

Photo-oxidation of Aromatic Hydrocarbons Produces Low-Volatility Organic Compounds
/ Wang, Mingyi (Carnegie Mellon U.) ; Chen, Dexian (Carnegie Mellon U.) ; Xiao, Mao (PSI, Villigen) ; Ye, Qing (Carnegie Mellon U.) ; Stolzenburg, Dominik (Vienna U.) ; Hofbauer, Victoria (Carnegie Mellon U.) ; Ye, Penglin (Aerodyne Research, Billerica) ; Vogel, Alexander L (Frankfurt U.) ; Mauldin, Roy L (U. Colorado, Boulder ; Carnegie Mellon U.) ; Amorim, Antonio (Lisbon U.) et al.
To better understand the role of aromatic hydrocarbons in new-particle formation, we measured the particle-phase abundance and volatility of oxidation products following the reaction of aromatic hydrocarbons with OH radicals. For this we used thermal desorption in an iodide-adduct Time-of-Flight Chemical-Ionization Mass Spectrometer equipped with a Filter Inlet for Gases and AEROsols (FIGAERO-ToF-CIMS). [...]

Molecular Composition and Volatility of Nucleated Particles from $\alpha$-Pinene Oxidation between −50 °C and +25 °C
/ Ye, Qing (Carnegie Mellon U. (main)) ; Wang, Mingyi (Carnegie Mellon U. (main)) ; Hofbauer, Victoria (Carnegie Mellon U. (main)) ; Stolzenburg, Dominik (Vienna U.) ; Chen, Dexian (Carnegie Mellon U. (main)) ; Schervish, Meredith (Carnegie Mellon U.

Helsinki (main)) ; Brilke, Sophia (Vienna U.) et al.
We use a real-time temperature-programmed desorption chemical-ionization mass spectrometer (FIGAERO–CIMS) to measure particle-phase composition and volatility of nucleated particles, studying pure α-pinene oxidation over a wide temperature range (−50 °C to +25 °C) in the CLOUD chamber at CERN. Highly oxygenated organic molecules are much more abundant in particles formed at higher temperatures, shifting the compounds toward higher O/C and lower intrinsic (300 K) volatility. [...]

Multicomponent new particle formation from sulfuric acid, ammonia, and biogenic vapors

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. [...]

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.

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. [...]

Role of iodine oxoacids in atmospheric aerosol nucleation
/ He, Xu-Cheng (Helsinki U.) ; Tham, Yee Jun (Helsinki U.) ; Dada, Lubna (Helsinki U.) ; Wang, Mingyi (Carnegie Mellon U.) ; Finkenzeller, Henning (U.

Iodic acid (HIO3) is known to form aerosol particles in coastal marine regions, but predicted nucleation and growth rates are lacking. Using the CERN CLOUD (Cosmics Leaving Outdoor Droplets) chamber, we find that the nucleation rates of HIO3 particles are rapid, even exceeding sulfuric acid–ammonia rates under similar conditions.

Aqueous phase oxidation of sulphur dioxide by ozone in cloud droplets

The growth of aerosol due to the aqueous phase oxidation of sulfur dioxide by ozone was measured in laboratory-generated clouds created in the Cosmics Leaving OUtdoor Droplets (CLOUD) chamber at the European Organization for Nuclear Research (CERN). Experiments were performed at 10 and −10 °C, on acidic (sulfuric acid) and on partially to fully neutralised (ammonium sulfate) seed aerosol. [...]

Highly oxidised organic vapors can effectively stabilize sulphuric acid in heteronuclear clusters and drive new-particle formation. We present quantum chemical calculations of cluster stability, showing that multifunctional species can stabilize sulphuric acid and also present additional polar functional groups for subsequent cluster growth.

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.
