Group of Atmospheric Aerosol Research (GAAR)

"Our mission is to get better knowledge of atmospheric aerosol particle distribution within the planetary boundary layer, aerosol properties, behaviour, sources and health impact.“


We are looking for cooperation with academic partners as well as public and private organizations in the fields of aerosol science relating to the actual environmental problems. We offer our high-qualified expertise in the following fields:

- methodology for air pollution source reconnaissance authorized by Ministry of the Environment of the Czech Republic

- technique of airborne profi ling of atmospheric aerosol particles within planetary boundary layer with the stress on chemistry/ physics of lower troposphere

- all togehter that might serve as the expert opinions and arguments for decision making on different levels of air quality administration.
