By Dr. Andreas Stohl
On 26 November 2026 at 6.00 pm, Dr. Andreas Stohl will give a public lecture in Vienna as part of the APRI Annual General Meeting.
Arctic aerosols can be of local origin or imported from the mid-latitudes. Not only do they cause air pollution in regions where one would not expect it, but they also have an impact on the climate, for example through the deposition of absorbing aerosols on snow and ice.

The influence of aerosols is strikingly evident in the so-called ‘Arctic Haze’ in spring. In his lecture, Andreas Stohl examines the various sources of aerosols in the Arctic, ranging from dust emissions within the Arctic itself, through the import of wildfire aerosols, to traditional anthropogenic air pollution.

He explains the impact of atmospheric transport on the Arctic aerosol budget and how this has already changed as a result of climate change. Finally, he demonstrates the importance of aerosol deposits in Arctic ice cores for reconstructing historical events dating back as far as ancient times.

His work focuses on the analysis and modelling of transport processes in the atmosphere and their impact on air quality and climate. During the 4th International Polar Year (2007–2008), he led the ‘core project’ POLARCAT.
The lecture will be held in German
