5. Recommended time/stage of studies for completion

Can be taken in the early or later stages of studies. However, it is recommended after the ATM347 Boundary Layer Physics I.

6. Term/teaching period when the course will be offered

The course will be offered every second year in the spring term.

7. Scope of the course in credits

5 cr

8. Teacher coordinating the course

Ivan Mammarella

9. Course learning outcomes

• You will learn to know the common techniques for measuring turbulent fluxes.
• You will learn how to process micrometeorological data and calculate fluxes of energy and any gases.
   

10. Course completion methods

Exercises, essay and final presentation. Exercises are mostly small programming tasks and sometimes theoretical ones ('pen and paper'). In the essay the student reports on one of the flux measurement technique, based on course material and other scientific articles. In the final presentation, the student synthesizes and discusses the results obtained during the exercises.

11. Prerequisites

• Basics of atmospheric boundary layer physics. Suitable course at the University of Helsinki is ATM347 Boundary Layer Physics I.
• Programming skillls in Matlab/Octave.
• Other courses related to turbulent flow (ATM333 Turbulence Theory) and time-series analysis (ATM310 Time Series Analysis in Geosciences) may be useful.

12. Recommended optional studies

If you are interested in continuing in the subject courses ATM321 Field Course in Micrometeorology and Hydrology and    ATM359 Eddy covariance intensive course   are recommended.

13. Course content

• Basics concepts and approaches to describe the turbulent flow in the atmospheric surface layer
•  Surface flux measurement techniques

·         Eddy covariance  

·         Disjunct eddy covariance 

·         Relaxed eddy accumulation 

·         Flux-gradient technique 

·         Modified Bowen ratio 

·         Bowen ratio method (for H₂O) 

·         Dissipation method

 ·        Bulk transfer relationships

14. Recommended and required literature

•  Lecture notes
• Supplementary reading:
  
  • Eddy covariance: a practical guide to measurement and data analysis / Marc Aubinet, Timo Vesala, Dario Papale, editors
• • Stull R.B. , 1988:  An introduction to Boundary-Layer Meteorology
  • Kaimal J. C. & Finnigan J. 1994: Atmospheric Boundary Layer Flows

15. Activities and teaching methods in support of learning

Weekly lectures and exercises (individual work). Final presentation based on exercise's results (individual).

16. Assessment practices and criteria, grading scale

The course is graded in scale 1 to 5. There will be no final exam and the grade is determined by following criteria:

•  60 % on exercise/final presentation points (30% of the exercise points needed to pass)
•  40 % on the essay
    

17. Teaching language

English.
