| 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 | M. Ammann, C. Heald, C. Mohr | ||||||||||||||||||||||||||||||||
| Abstract | This is a self-study course targeted at Master students who did not follow the bachelor course "atmospheric chemistry" or equivalent, providing a general introduction into atmospheric chemistry. It introduces the relevant fundamental concepts, which are explored in the context of key environmental issues, such as air pollution, stratospheric ozone depletion, and connections to climate change. | |||||||||||||||||||||||||||||||||||
| Learning objective | At the end of this course, students are able to: 1. describe the structure of the atmosphere and list atmospheric components and their main properties 2. define and describe the chemical and physical processes in the stratosphere and troposphere, follow reaction mechanisms, and apply rate laws 3. describe the physical and chemical principles of air pollution and summarize the most important legislative measures 4. discuss the local, regional, and global aspects of interactions between air quality, ecosystem health, and climate | |||||||||||||||||||||||||||||||||||
| Content | - Origin and properties of the atmosphere: composition (gases and aerosols), atmospheric structure, UV radiation, transport timescales. - Kinetics of gas phase reactions: rate laws, mechanisms of bimolecular and termolecular reactions. - Stratospheric chemistry: Chapman cycle, catalytic ozone destruction cycles, polar ozone hole, Montreal protocol. - Tropospheric chemistry: oxidizing capacity of the troposphere and the role of OH, oxidation and global budgets of CO and CH4, role of NOx, and the global tropospheric O3 budget. - Surface ozone chemistry: HOx-NOx cycle, role of VOCs, O3 isopleth, ozone production efficiency. - Aerosols: primary and secondary sources, composition, quantities and measures, connections to climate. - Multiphase chemistry: solubility of gases, Raoult’s Law and hygroscopicity, kinetics of gas to particle transfer, N2O5 chemistry, aqueous phase sulfur chemistry, secondary organic aerosol formation. - Air quality: role of planetary boundary layer, deposition processes, summer- versus winter-smog, environmental problems, legislation, long-term trends. - Global aspects: air quality - climate interactions. | |||||||||||||||||||||||||||||||||||
| Lecture notes | The slides, notes and exercises of the preceding edition of the bachelor course 701-0471-01L Atmospheric Chemistry will be provided. | |||||||||||||||||||||||||||||||||||
| Prerequisites / Notice | Basic education in chemistry and physics are expected | |||||||||||||||||||||||||||||||||||

| 701-1214-00L | Atmospheric Chemistry and Global Change Class requires a minimum of 8 students to be enrolled | 4 credits | 2V + 1U | C. Heald | ||||||||||||||||||||||||||||||||
| Abstract | In this course we will explore how atmospheric chemical composition both drives and responds to changes in the earth system, including climate change. We will discuss recent advances and key uncertainties in our understanding of the processes that control the abundance of reactive gases and aerosols in the atmosphere and their interaction with global change. | |||||||||||||||||||||||||||||||||||
| Learning objective | After this course, students will be able to: • critically read and summarise recent literature in atmospheric chemistry • explain the key drivers of past and future changes in atmospheric composition • evaluate how uncertainties in relevant atmospheric chemistry processes may impact projections of future atmospheric composition • design an original research proposal | |||||||||||||||||||||||||||||||||||
| Content | This class builds on fundamental understanding of atmospheric chemistry to explore how atmospheric chemistry interacts with global change, both past and future. Lectures cover a range of topics and are complemented by literature discussions. Specific topics include: fires, land use change, biogenic organics, carbonaceous aerosol, nitrogen, sulphur, methane, dust and metals, air quality and climate, and geoengineering. The class concludes with students developing and presenting a novel research proposal based on the topics discussed in class. | |||||||||||||||||||||||||||||||||||
| Literature | IPCC Sixth Assessment Report, Working Group 1 Report “The Physical Science Basis” (available online: http://www.ipcc.ch/report/ar6/wg1/ ). All other material will be taken from the recent literature. | |||||||||||||||||||||||||||||||||||
| Prerequisites / Notice | Bachelor’s level Atmospheric Chemistry (701-0471 or similar) is required. | |||||||||||||||||||||||||||||||||||
