About GAeF

The "Gesellschaft für Aerosolforschung e.V." (GAeF) was founded in 1972 in order to promote all areas of aerosol research, to provide information on an interdisciplinary basis amongst members and the public, to provide an international forum for collaboration and support scientific education and teaching at all levels. GAeF has member from all over the world and encourages aerosol scientists to join the society.

EAA Working Groups


Speakers of the working groups are Birgit Wehner (birgit[at]tropos.de) and Ulas Im (ulas[at]envs.au.dk).


WG 1: Aerosol Technology


WG chairs



WG 2: Atmospheric Aerosol Studies (AAS)


WG description

Ambient aerosols are recognized to have important impacts on the ecosystem, human health and climate change. However, aerosol formation and aging mechanisms, as well as a number of related atmospheric processes are not well understood. Of our main interest are physical, chemical, and optical properties of ambient aerosols and their mimics, including time-resolved investigations of the complex multiphase system and aerosol modelling. We aim to provide better insight, new aspects and knowledge on the lifecycle of atmospheric aerosol particles, with an emphasis on their roles in cloud formation and Earth’s radiative balance.


The Atmospheric Aerosol Studies working group is a highly interdisciplinary scientific forum that strives for the scientific exchange and the highest-level scientific discussions within the wide atmospheric aerosol science community. We warmly welcome contributions from field as well as aerosol chamber, laboratory, and modelling studies considering any aspect of atmospheric aerosols and their processing.
