New research results change the understanding of atmospheric aerosol properties and climate effects
Date:10/14/2010

Atmospheric fine particles affect the Earth's radiation balance by interacting with solar radiation and by participating in cloud formation. Biogenic volatile organic compounds are key players in new particle formation processes. Hence, terrestrial vegetation has an important role as the newly formed particles cool our climate. The chemical composition of such secondary organic aerosol (SOA) particles formed from volatile compounds emitted by vegetation is very complicated and only limited information on the phase state of SOA particles has been available. Thus the scientific community has tried to understand the chemical composition and physical characteristics of SOA particles in order to better understand their climatic implications and also to enable more accurate predictions using global climate models.

Until now, biogenic SOA particles have been represented as liquid droplets in global climate models. But according to the new research published in Nature, the physical state of SOA particles formed in coniferous forest is solid, most likely glassy soon after their formation.

-One can figure these aerosol particles as tiny children's glass marbles, says Professor Thomas Koop from Bielefeld University, Germany.

The experimental research has been conducted by the group of scientists from Finnish and German universities and institutes (Tampere University of Technology, University of Eastern Finland, Finnish meteorological institute, University of Helsinki, Bielefeld University, and Max Planck Institute for Chemistry). The discovery was made in University of Eastern Finland's experimental laboratory designed by Dr Jorma Joutsensaari.

In the experiments, fine particles formed from volatile compounds emitted by scots pines were studied under controlled conditions, and additional measurements were carried out in a coniferous fore
