KurzbeschreibungThis course provides a general introduction into atmospheric chemistry targeted at master students who did not follow the bachelor course "atmospheric chemistry" or equivalent.
LernzielThe learning target of this course is a general overview on the most important processes of atmospheric chemistry and the various problems of the anthropogenic impact on the chemical composition of the atmosphere and air quality.
Inhalt- Physical 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.
- Photochemistry: Photolysis frequencies, O3 formation,...
- Aerosols and clouds: chemical properties, primary and secondary aerosol sources
- Multiphase chemistry: heterogeneous kinetics, solubility and hygroscopicity, N2O5 chemistry, SO2 oxidation, secondary organic aerosols
- Deposition: dry and wet deposition, acid rain,...
- Air quality: Environmental problems, legislation, sources, trends
- Stratospheric chemistry: Chapman cycle, Brewer-Dobson circulation, catalytic ozone destruction cycles, polar ozone hole, Montreal protocol
Global aspects: global budgets, air quality - climate interactions
