TL;DR: Three separate size regimes below 2-nm diameter are identified that build up a physically, chemically, and dynamically consistent framework on atmospheric nucleation—more specifically, aerosol formation via neutral pathways.
Journal ArticleDOI
Aerosol chemical composition in cloud events by high resolution time-of-flight aerosol mass spectrometry.
Liqing Hao,Sami Romakkaniemi,Aki Kortelainen,A. Jaatinen,Harri Portin,Harri Portin,Pasi Miettinen,Mika Komppula,A. Leskinen,Annele Virtanen,James N. Smith,Donna Sueper,Douglas R. Worsnop,Douglas R. Worsnop,Kari E. J. Lehtinen,Kari E. J. Lehtinen,Ari Laaksonen,Ari Laaksonen +17 more
TL;DR: The results indicate a possible joint effect of activation ability of aerosol particles, cloud processing, and particle size effects on cloud formation.
The evolution of nucleation- and Aitken-mode particle compositions in a boreal forest environment during clean and pollution-affected new-particle formation events
Petri Vaattovaara,Tuukka Petäjä,Jorma Joutsensaari,Pasi Miettinen,Boris Zaprudin,Aki Kortelainen,Juha Heijari,Pasi Yli-Pirilä,Pasi Aalto,D. R. Worsnop,Ari Laaksonen +10 more
TL;DR: Petrivaattovaattovaara et al. as mentioned in this paper proposed a method to detect the presence of hurricanes in the Finnish Meteorological Institute (FMI) data set, which can be used for forecasting the weather in Finland.
Journal ArticleDOI
Real-Time Chemical Composition Analysis of Particulate Emissions from Woodchip Combustion
Aki Kortelainen,Jorma Joutsensaari,Liqing Hao,Jani Leskinen,Petri Tiitta,A. Jaatinen,Pasi Miettinen,Olli Sippula,Tiina Torvela,Jarkko Tissari,Jorma Jokiniemi,Douglas R. Worsnop,James N. Smith,Ari Laaksonen,Annele Virtanen +14 more
TL;DR: In this paper, a moving step-grate burner was used for wood chips combustion in different combustion conditions (efficient, intermediate, and smoldering) in the laboratory and the particulate emissions were measured with an Aerodyne high-resolution time-of-flight aerosol mass spectrometer (HR-TOF-AMS).
Sources of particulate organic nitrates in the boreal forest in Finland
