|Semester||Spring Semester 2021|
|Lecturers||D. W. Brunner, I. El Haddad|
|Periodicity||yearly recurring course|
|Language of instruction||English|

|Abstract||The course gives an overview tropospheric chemistry, which is based on laboratory studies, measurements and numerical modelling. The topics include aerosol, photochemistry, emissions and depositions. The lecture covers urban-regional-to-global scale issues, as well as fundamentals of the atmospheric nitrogen, sulfur and methane cycles and their contributions to aerosol and oxidant formation.|
|Objective||Based on the presented material the students are expected to understand the most relevant processes responsible for the anthropogenic disturbances of tropospheric chemical composition. The competence of synthesis of knowledge will be improved by paper reading and student's presentations. |
These presentations relate to a particular actual problem selected by the candidates.
|Content||Starting from the knowledge acquired in lecture 701-0471, the course provides a more profound view on the the chemical and dynamical process governing the composition and impacts of air pollutants like aerosol and ozone, at the Earth's surface and the free troposphere. |
Specific topics covered by the lecture are: laboratory and ambient measurements in polluted and pristine regions, the determination of emissions of a variety of components, numerical modelling across scales, regional air pollution - aerosol, and photooxidant in relation to precursor emissions,
impacts (health, vegetation, climate), the global cycles of tropospheric ozone, CH4, sulfur and nitrogen components.

|Prerequisites / Notice||The basics in physical chemsitry are required and an overview equivalent to the bachelor course in atmospheric chemsitry (lecture 701-0471-01) is expected.|
|Performance assessment information (valid until the course unit is held again)|
|Performance assessment as a semester course|
|ECTS credits||3 credits|
|Examiners||D. W. Brunner, I. El Haddad|
|Language of examination||English|
|Repetition||The performance assessment is offered every session. Repetition possible without re-enrolling for the course unit.|
|Mode of examination||oral 30 minutes|
|Additional information on mode of examination||The final grade is determined by: Oral exam (2/3) and presentation (1/3, compulsory continuous performance assessment). Additionally the final grade can be improved (up to 0.25 grade points) by two learning tasks. |
The language of the oral exam can be changed to German (request of student)
Compulsory continuous performance assessment:
One student presentation. For the presentation the students (groups of 2 or 3) select a topic from a list, prepare a 20 minutes presentation (based on a literature search).
Voluntary Learning tasks:
One modelling exercise on photochemical limitation regimes.
Three paper discussions. The students will have one month time to collectively comment on a paper using tools for online collaboration and
feedbacks. The students’ comments will be finally discussed during the lecture.
|This information can be updated until the beginning of the semester; information on the examination timetable is binding.|
