| 701-0471-AAL | Atmospheric Chemistry  Enrolment ONLY for MSc students with a decree declaring this course unit as an additional admission requirement. Any other students (e.g. incoming exchange students, doctoral students) CANNOT enrol for this course unit. | 3 credits | 6R | D. W. Brunner, M. Ammann | |
| Abstract | This 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. | ||||
| Learning objective | The 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 - Multiphase chemistry: heterogeneous 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 / Notice | Basic courses in chemistry and physics are expected | ||||
| 701-0471-01L | Atmospheric Chemistry | 3 credits | 2G | M. Ammann, D. W. Brunner | |
| Abstract | The lecture provides an introduction to atmospheric chemistry at bachelor level. It introduces the kinetics of gas phase and heterogeneous reactions on aerosols and in clouds and explains the chemical and physical mechanisms responsible for global (e.g. stratospheric ozone depletion) as well as regional (e.g. urban air pollution) environmental problems. | ||||
| Learning objective | The students will understand the basics of gas phase and heterogeneous reactions and will know the most relevant atmospheric chemical processes taking place in the gas phase as well as between different phases including aerosols and clouds. The students will also acquire a good understanding of atmospheric environmental problems including air pollution, stratospheric ozone destruction and changes in the oxidative capacity of the global atmosphere. | ||||
