AbstractThis is a self-study course targeted at Master students who did not follow the bachelor course "atmospheric chemistry" or similar. The course provides a general introduction into atmospheric chemistry.
ObjectiveThe learning target of this lecture is a general overview on the most important processes of atmospheric chemistry and the various problems of the anthropogenic change in the structure of Earth's atmosphere.
Content- Origin and properties of the atmosphere: structure, large scale dynamics, UV radiation
- Thermodynamics and kinetics of gas phase reactions: enthalpy and free energy of reactions, rate laws, mechanisms of bimolecular and termolecular reactions.
- Tropospheric photochemistry: Photolysis reactions, photochemical O3 formation, role and budget of HOx, dry and wet deposition
- Aerosols and clouds: chemical properties, primary and secondary aerosol sources, phase transfer kinetics, solubility and hygroscopicity, N2O5 chemistry, SO2 oxidation, secondary organic aerosols
- Air quality: role of planetary boundary layer, summer- versus winter-smog, environmental problems, legislation, long-term trends
- Stratospheric chemistry: Chapman cycle, Brewer-Dobson circulation, catalytic ozone destruction cycles, polar ozone hole, Montreal protocol
- Global aspects: global budgets of ozone, methane, CO and NOx, air quality - climate interactions
Prerequisites / NoticeBasic courses in chemistry and physics are expected

AbstractThe lecture provides an introduction to atmospheric chemistry at bachelor level. It introduces the fundamentals of gas phase reactions, the concept of solubility and reactions in aerosols and in clouds. It explains the chemical and physical processes responsible for global (e.g. stratospheric ozone depletion) as well as regional (e.g. urban air pollution) environmental problems.
ObjectiveThe students will understand the basics of gas phase reactions and of reactions and processes in aerosols and clouds. The students will understand the most important chemical processes in the troposphere and the stratosphere.
The students will also acquire a good understanding of atmospheric environmental problems including air pollution, tropospheric ozone formation, stratospheric ozone destruction and the relationship between air pollution and climate change.
Content- Origin and properties of the atmosphere: composition (gases and aerosols), structure, large scale dynamics, UV radiation
- Thermodynamics and kinetics of gas phase reactions: enthalpy and free energy of reactions, rate laws, mechanisms of bimolecular and termolecular reactions.
- Tropospheric photochemistry: Photolysis reactions, photochemical O3 formation, role and budget of HOx, dry and wet deposition
- Aerosols and clouds: chemical properties, primary and secondary aerosol sources, solubility of gases, hygroscopicity, kinetics of gas to particle transfer, N2O5 chemistry, SO2 oxidation, secondary organic aerosol formation
- Air quality: role of planetary boundary layer, summer- versus winter-smog, environmental problems, legislation, long-term trends
- Stratospheric chemistry: Chapman cycle, Brewer-Dobson circulation, catalytic ozone destruction cycles, polar ozone hole, Montreal protocol
- Global aspects: global budgets of ozone, methane, CO and NOx, air quality - climate interactions
Lecture notesLecture materials (slides) are provided continuously during the semester, at least 2 days before each lecture.
Prerequisites / NoticeAttendance of the lecture "Atmosphäre" LV 701-0023-00L or equivalent knowledge is a pre-requisite, and basic courses in physics and chemistry are expected.

On Mondays (or upon agreement) a tutorial is offered. This allows the students to discuss unresolved issues from the lecture or to discuss the problems of the exercise series and their solution. Participation is recommended.
