The subject Atmospheric chemistry deals with the problematics of the composition of Earth's atmosphere and especially the physico-chemical processes that take place in it. In the introductory lecture the students are familiarized with the atmosphere stratification, its properties and importance of individual layers, as well as with the chronostratigraphic history of Earth and its atmosphere. Furthermore, students are acquainted with the technical and legal issues, connected with building up and operation of environmental information systems. The content of the subject is divided thematically into three inter-related areas. The first area is more focused on physical processes in the atmosphere. The principles of circulation in the atmosphere are discussed with regard to the main forces of air masses movement, formation, importance and types of cloud cover. The second area is aimed at the most important mechanisms of atmospheric reactions and their specificity. Among the reactions the most significant examples are described, such as photochemical, acid-base and nuclear atmospheric reactions. Especially tropospheric, but also stratospheric processes are presented. Separately reactions, taking place in tropospheric background in both day and night phase, are showed to the audience. Special attention is paid to the reactions of hydroxyl, hydroperoxyl and nitrate radical. The third topic deals with the anthropogenic effect on climate. The distribution of pollutants according to various criteria is given. Consequences of the emissions of the most important groups of pollutants are demonstrated together with mechanisms of their impact as well as processes leading to their decomposition in the atmosphere. A separate lecture is devoted to the issue of greenhouse gases and smog formation.

The essential condition for the successful finishing the course is accomplishing the examination, composed of a written test and verbal demonstrating of the knowledge of one theme, randomly selected from the list. The student must correctly answer at least 50 % of the questions in the test as well as verbally answer at least 50 % of the sub-questions, which the theme consists of.

Students will be able to: Upon completing the course of Atmospheric Chemistry students should have improved knowledge of organic chemistry and meteorology - namely situations related to worsened dispersion conditions of chemical pollutants in atmosphere. Current state of Czech as well as international legislation concerning emissions, imissions, indoor air pollution and occupational environment is covered. Graduates should be well informed about transboundary transfer of air pollution, acid rain, stratospheric destruction of ozone layer, greenhouse effect and both acid and photochemical smog situations.
