Anna Novelli,Anna Novelli,K. Hens,Cheryl Ernest,Cheryl Ernest,Monica Martinez,A. C. Nölscher,A. C. Nölscher,Vinayak Sinha,Pauli Paasonen,Tuukka Petäjä,Mikko Sipilä,Thomas Elste,Christian Plass-Dülmer,Gavin Phillips,Gavin Phillips,Dagmar Kubistin,Dagmar Kubistin,Jonathan Williams,Luc Vereecken,Luc Vereecken,Jos Lelieveld,Hartwig Harder +22 more
TL;DR: In this paper, the authors analyzed the extensive dataset from the HUMPPA-COPEC 2010 and the HOPE-2012 field campaigns in the boreal forest and rural environments of Finland and Germany, respectively, and estimated the abundance of stabilised Criegee intermediates in the lower troposphere.
Journal ArticleDOI
Aerosols and nucleation in eastern China: first insights from the new SORPES-NJU station
Erik Herrmann,Erik Herrmann,Erik Herrmann,Aijun Ding,V.-M. Kerminen,Tuukka Petäjä,Xiu-Qun Yang,Jianqi Sun,Ximeng Qi,Hanna E. Manninen,Jani Hakala,Tuomo Nieminen,P. P. Aalto,Markku Kulmala,Congbin Fu +14 more
TL;DR: In this article, the authors measured air ions in the diameter range 0.8-42 nm using an air ion spectrometer, and a differential mobility particle sizer (DMPS) provided particle number size distributions between 6 and 800 nm.
Journal ArticleDOI
Horizontal homogeneity and vertical extent of new particle formation events
Birgit Wehner,Holger Siebert,Frank Stratmann,Thomas Tuch,Alfred Wiedensohler,Tuukka Petäjä,Miikka Dal Maso,Markku Kulmala +7 more
TL;DR: In this article, the occurrence of ultrafine particles was investigated simultaneously at four ground-based measurement sites, where the maximum distance between the sites was 50 km and the vertical profiles of aerosol particles from 5-10 nm were measured by a tethered-balloon-borne system.
Journal ArticleDOI
Applicability of condensation particle counters to measure atmospheric clusters
Mikko Sipilä,Mikko Sipilä,Katrianne Lehtipalo,Markku Kulmala,Tuukka Petäjä,Tuukka Petäjä,Heikki Junninen,Pasi Aalto,Hanna E. Manninen,Ella-Maria Kyrö,E. Asmi,Ilona Riipinen,Joachim Curtius,Andreas Kürten,Andreas Kürten,Stephan Borrmann,Colin D. O'Dowd +16 more
TL;DR: In this paper, an evaluation of a pulse height condensation particle counter (PH-CPC) and an expansion Condensation Particle Counter (EPC) in terms of measuring ambient and laboratory-generated molecular and ion clusters is presented.
Journal ArticleDOI
