Aims of the module and acquired skills

  • Comprehension of how physical/chemical processes affect composition and changes of the atmosphere
  • Knowledge of several trace substance cycles
  • Comprehension of spatial and temporal gradients of trace substances
  • Application of reaction mechanisms on the decomposition of trace substances
  • Acquired skills are computer practice, general comprehension of systems, critical assessment and discussion of scientific work

Type of module examinations

Written Examination (graded)

7 Requisites for the allocation of credits

Successful participation in the exercises (50 % of the possible points have to be obtained) and passing of the examination.

At the end of the semester or the beginning of the following semester a possibility to repeat the examination is offered. A failed examination may be repeated twice. Additional possibilities to repeat an examination exist according to the examination regulations (§ 20 section 1).

Assessments which have been passed are not allowed to be taken again, with one exception: If at the end of a module which consists of a lecture and tutorial classes, the student takes the assessment at the first available date after having received admission to the module exam, he/she is then allowed to take the examination again at the next available date for the purpose of improving the grade, even if he/she passed the assessment the first time – in this case, the better of the two grades will count towards the final degree grade (§ 20 section 9).

The module mark is the grade obtained in the assessment. In the case of two passed assessments the module mark is the better grade
8 Compatibility with other Curricula
  • Other modules of equal value can be admitted and announced by the examination board after agreement.
  • Suitable as an elective course for mathematics, physics and geoscience students
