Journal ArticleDOI
Flood or drought: How do aerosols affect precipitation?
Daniel Rosenfeld,Ulrike Lohmann,Graciela B. Raga,Colin D. O'Dowd,Markku Kulmala,Sandro Fuzzi,Anni Reissell,Meinrat O. Andreae +7 more
TL;DR: A conceptual model is proposed that explains this apparent dichotomy of pristine tropical clouds with low CCN concentrations rain out too quickly to mature into long-lived clouds and heavily polluted clouds evaporate much of their water before precipitation can occur.
Journal ArticleDOI
A new feedback mechanism linking forests, aerosols, and climate
Markku Kulmala,Tanja Suni,Kari E. J. Lehtinen,M. Dal Maso,Michael Boy,Anni Reissell,Anni Reissell,Üllar Rannik,Pasi Aalto,Petri Keronen,Hannele Hakola,Jaana Bäck,Thorsten Hoffmann,Timo Vesala,Pertti Hari +14 more
TL;DR: In this paper, the authors investigated the connection between forest-atmosphere carbon exchange and aerosol dynamics in the continental boundary layer by means of multiannual data sets of particle formation and growth rates, of CO2 fluxes, and of monoterpene concentrations in a Scots pine forest in southern Finland.
Journal ArticleDOI
Sulphuric acid closure and contribution to nucleation mode particle growth
Michael Boy,Markku Kulmala,T. M. Ruuskanen,Mari Pihlatie,Anni Reissell,Pasi Aalto,Petri Keronen,M. Dal Maso,Heidi Hellén,Hannele Hakola,R. Jansson,M. Hanke,Frank Arnold +12 more
TL;DR: In this article, the authors measured and calculated sulphuric acid concentrations based on pseudo steady state model with corresponding measurements of CO, NOx, O3, SO2, methane and non-methane hydrocarbon (NMHC) concentrations as well as solar spectral irradiance and particle number concentrations with size distributions.
Journal Article
Long-term measurements of surface fluxes above a Scots pine forest in Hyytiala, southern Finland, 1996-2001
Tanja Suni,Janne Rinne,Anni Reissell,Nuria Altimir,Petri Keronen,Üllar Rannik,M. Dal Maso,Markku Kulmala,Timo Vesala +8 more
TL;DR: Nearly six years of measurements of surface fluxes of momentum, sensible heat, water vapour, carbon dioxide and aerosol particles, along with a three-month time series of ozone flux, measured by eddy covariance above a Scots pine forest in southern Finland from April 1996 to December 2001 are presented.
Journal ArticleDOI
Formation of acetone from the OH radical‐ and O3‐initiated reactions of a series of monoterpenes
TL;DR: In this article, the formation yields of acetone from the gas phase reactions of the OH radical and O3 with a series of monoterpenes have been measured at room temperature and atmospheric pressure of air.
