WG 2: Atmospheric Aerosol Studies


Chair: Ana Kroflič

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.


​​Subtopics (incl. responsible person and short description)


  1. Aerosols and clouds in polar regions (Julia Schmale). This topic covers field, model and laboratory studies relevant to all aerosol characteristics and aerosol-cloud interactions in polar regions (Arctic, Antarctica, Southern Ocean). Interdisciplinary studies that link aerosols and clouds to polar specific environmental factors are highly welcome.

  2. New particle formation (Jenni Kontkanen). This topic covers contributions on laboratory and field experiments, and modelling studies on the formation and growth of atmospheric aerosol particles.

  3. Aerosol-cloud-interaction in warm, mixed-phase and ice clouds (Silvia Henning). This topic covers atmospherically relevant laboratory and model studies as well as short and long-term studies in the field which focus on particle hygroscopicity, CCN and INP activity, primary vs. secondary ice production and their interaction with cloud turbulence and microphysics.

  4. Transport of atmospheric aerosols, modelling and climate forcing (Ulas Im). This topic covers measurement and regional/global modelling studies on the transport of atmospheric aerosols and their impacts on regional and global aerosol levels, radiative forcing and climate. The models can range from regional to global chemistry and transport models, to climate and Earth system models.

  5. Molecular characterization of atmospheric aerosols (Christopher Kampf). This topic covers molecular level identification and quantification of atmospheric aerosol constituents in laboratory and field studies using spectroscopic, magnetic resonance, and mass spectrometric methods. Presentations on the analysis of individual compounds, compound classes, and complex mixtures are welcome.

  6. Homogeneous, heterogeneous and multiphase chemistry, secondary aerosols (Ana Kroflič). The focus of this topic is on the understanding of chemical processes governing properties of atmospheric aerosols, their formation and aging. Interdisciplinary studies that link aerosol composition to their (changing) properties are highly welcome. Related contributions on laboratory and chamber experiments, field campaigns, as well as modelling studies are anticipated.

  7. Optical properties, remote sensing, black and brown carbon (Luca Ferrero). This topic covers field, model and laboratory studies relevant to all aerosol optical properties. Remote sensing of aerosol optical properties and their radiative impact as well as remote sensing retrieval of ground PM concentration are welcome. A special attention is given to light absorbing aerosols (i.e. black and brown carbon but also dust) and interdisciplinary studies that link aerosol optical properties to their size, chemistry and/or sources are highly welcome.

  8. Sources and source apportionment of atmospheric aerosols (Daniele Contini). This topic welcomes contributions on the identification and characterisation of aerosol sources using both source-oriented and receptor-oriented models.

  9. Physico-chemical properties of atmospheric aerosols (all). This topic covers contributions that screen a wide variety of aerosol properties in order to advance the understanding of the complex system of atmospheric aerosol. Laboratory and field research that does not fit in any of the above topics is welcome.

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 members from all over the world and encourages aerosol scientists to join the society.
