Our group covers a broad spectrum of topics, mainly focusing on tropospheric gas and aerosol phase chemistry.

The main current topics are:


Impact of emissions on atmospheric composition

In our group we focus on the impact of natural, biogenic and anthropogenic emissions on the chemical properties of the atmosphere. We use numerical model to optimize present-day emissions based on observations as well as to investigate the outcomes of various emissions scenarios.

Oxidation capacity of the atmosphere

The self-cleaning or oxidation capacity of the atmosphere is essential for the removal of pollution in the troposphere. In our group we study the formation and the factors governing the concentration of radicals in the atmosphere, with special focus on hydoxyl radicals (OH), the main radical present in the atmosphere. With numerical simulation we investigate the OH reactivity and the process which controls OH (and other radicals) concentration.

Aerosols nucleation and growth on global scale

Aerosol particles influence climate through aerosol–cloud and aerosol–radiation interactions. A detailed understanding of the sources of aerosol particles is necessary to study their climate and health effects. In our group we study the aerosols budget on a global scale, with special focus on new particle formation (NPF), i.e. nucleation and growth of new aerosol particles from vapours, which is an important source of secondary aerosol particles in the troposphere and planetary boundary layer.

Air pollution and its health burden

Long term exposure of air pollution in general, and fine particulate in particular, can have effect on human health. This has been proved by multiple epidemiological studies, although the magnitude of the impact remains difficult to quantify. In our group, we investigate the effect of pollution and its contributing factors to the human health on a global scale.
