Changes in the course due to coronavirus

As a general rule, exams at the MN Faculty will during the autumn of 2021 be conducted without physical attendance. For reasons relating to the course content, some courses will have on-campus written examination if the current infection rate makes this possible.

The semester page for your course will be updated with any changes in the form of examination. See also more information about examination at the MN Faculty in 2021.

Course content

The course deals with the basic processes that govern the composition of chemically active species in the atmosphere (gases and aerosols). This is crucial in understanding trends in short-lived greenhouse gases, aerosols, ozone depletion in the stratosphere, acidification and regional air pollution. The course gives an introduction to modelling of atmospheric chemistry in e.g. Earth System Models.

Learning outcome

The student will obtain a basic knowledge of

  • the photochemical processes that determine the oxidation capacity of the atmosphere
  • formation and loss of ozone in the stratosphere
  • chemical kinetics of gases
  • the impact of natural and anthropogenic emissions on concentrations of short-lived climate forcers
  • the formation of secondary aerosols
  • simple numerical models for atmospheric chemistry
