-Specification of the teaching period when the course will be offered

7. Scope of the course in credits

5 cr

8. Teacher coordinating the course

Annalea Lohila and Timo Vesala

9. Course learning outcomes


  • describe the physical and biological processes driving the heat and mass exchange of forests, wetlands and lakes with the atmosphere
  • explain how these processes are linked to water, carbon and nitrogen cycles
  • apply the gained knowledge in solving problems related to biogeochemical cycles
  • analyze the real field on the phenomena


10. Course completion methods

Weekly lectures and exercises. Zoom calculus circle organized for helping with the exercises. Attendance of lectures is not mandatory except for the last lecture + exercise (7.4.2021 at 12-16) when a poster seminar is organized

Learning diary which is returned in two parts with peer- and self-assessment. Poster synthesizing scientific articles completed as a group work. Common poster seminar in the end of the course (participation mandatory).

Completion requirements: 30% of the exercise problems to be solved. Problems are theoretical ones (pen-and-paper) and small programming tasks for analyzing data. Participation on poster preparation and seminar. Writing learning diary and assessing diaries of other students.

15. Activities and teaching methods in support of learning


Weekly lectures and exercises. Writing of a learning diary after each lecture and exercise and delivering it in the mid-course and in the end of the course. Poster group work based on scientific articles, poster seminar with the feedback in the end of the course. Assessment matrices are provided for the learning diary and the poster presentation.
