The aim of the course is to give students a comprehensive overview of the physico-chemical processes taking place in the troposphere and stratosphere. Even processes in higher atmospheric layers are not omitted. The content of the subject includes physico-chemical characterization of the atmosphere as a dynamic system, focuses on the thermal balance of the planet and the distribution of temperature within atmospheric stratification and a detailed description of the mechanisms of greenhouse gases and vapors. The subsequent part of the subject is strictly chemical and deals with reactions in clean troposphere, especially photooxidation reactions as well as reactions with hydroxyl radicals. Since anthropogenic sources of emissions are detrimental to important atmospheric functions, the significant part of the subject clarifies chemistry of the most important pollutants in the troposphere. Namely reactions of the following substances are described in more details: gases with acidic reaction, hydrocarbons and their derivatives and separately the wide group of greenhouse gases. Among other things mechanism of stratospheric destruction of ozone is discussed.

Students will acquire the following knowledge by successfully completing the course: physical rules of energy and mass exchange within the individual atmospheric stratification layers, global and local flows, such as transport of atmospheric water, formation of precipitations and other processes, important also for long range transfer of pollutants. Students will also understand the mechanisms of atmospheric conversion of organic and inorganic pollutants. Among other things, they will be more familiar with cycles of natural formation and depletion of tropospheric ozone, as well as in detail with the chemistry of ozone decomposers. Likewise, students will know the mechanisms of day and night reactions that take place in the clean troposphere.

The content of the doctoral subject is divided into three consecutive units. The first part focuses on the physical laws in individual layers of atmospheric stratification. Students are acquainted in more details with the transport of energy and matter especially in the troposphere and stratosphere. Together with the description of global and local atmospheric flows, as well as the mechanisms contributing to formation of precipitations, methodology of synoptic meteorology is presented. As a part of the explanation of meteorological methods, ways of elaborating short-, medium- and long-term forecasts, including predictions of the global climate evolution, are defined separately. The second part of the subject focuses on the mechanisms of homogeneous and heterogeneous atmospheric reactions, occurring especially in the stratosphere and in the pure troposphere. Separately acid-base and photochemical reactions are discussed. Particular attention is paid to reactions involving atomic oxygen, hydroxyl radical, hydroperoxyl radical and nitrate radical. The third and last part of the subject deals with chemistry of pollutants emitted by anthropogenic sources. Namely volatile organic compounds, acid gases, chlorinated, chlorofluorocarbons and fluorocarbons and other derivatives are solved. Special chapters deal with mechanisms of activity and decomposition of greenhouse gases and chemistry of stratospheric ozone layer destruction.
