Course description
Course content
Learning outcome
After taking this course, you will have obtained 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
In addition, you have gotten experience in presenting a scientific paper to your fellow students.
Admission to the course
PhD candidates from the University of Oslo should apply for classes and register for examinations through Studentweb.
If a course has limited intake capacity, priority will be given to PhD candidates who follow an individual education plan where this particular course is included. Some national researchers’ schools may have specific rules for ranking applicants for courses with limited intake capacity.
PhD candidates who have been admitted to another higher education institution must apply for a position as a visiting student within a given deadline.
Recommended previous knowledge
Overlapping courses
- 5 credits overlap with GEO4904 – Atmospheric Chemistry.
- 5 credits overlap with GEF2210 – Regional and global air pollution (discontinued).
- 3 credits overlap with GEO4928 – Clouds and Chemistry (discontinued).

Teaching
2 hours of lectures and up to 2 hours of exercises per week. 2 mandatory assignments must be approved prior to the final exam. PhD candidates are in addition required to give a seminar on a selected scientific paper.
Attendance at the first lecture is compulsory. Students who fail to meet are considered to have withdrawn from the course unless they have previously given notice to the course responsible.
We reserve the right to change the teaching form and examination of the course in semesters where 5 or fewer students have been admitted.
Examination
- 2 mandatory assignments and the lectured seminar on a scientific paper must be approved before you can sit the final examination.
- A final oral exam counts 100% towards the final grade.
It is possible to take the exam up to 3 times. If you withdraw from the exam after the deadline or during the exam, this will be counted as an examination attempt.
It will also be counted as 1 of the 3 attempts to sit the exam for this course if you sit the exam for the following course:
