Units courses prerequisite and corequisite
Prerequisite or corequisite units are presented within each program
Learning unit contents
Ecosystem energy balance:
- identification of the balance terms
- Bowen ratio
- stomatal and canopy conductance
- Atmospheric transport by turbulence:
- characterisation of the atmospheric boundary layer
- spectral characteristics of turbulence
- Monin Obukhov's theory of similarity
- calculation of aerodynamic resistance
Ecosystem carbon balance:
- identification of the balance terms
- temporal variations and determinism of photosynthesis, respiration and net fluxes
- modeling of fluxes at leaf scale
Ecosystem water balance:
- identification of the balance terms
- temporal variations and determinism of water fluxes
- water use efficiency
- forest ecosystem modelling
- use of stable water isotopes
Ecosystem nitrogen balance
Methodology of gas exchange measurement:
- description of analytical methods for measuring trace gas concentration
- micrometeorological method of eddy-covariance
- radiation measurements
Learning outcomes of the learning unit
After completing the course the student is expected to be able to:
- Describe the different balance terms
- Explain the functioning of the ecosystem studied and the dynamics of its exchanges at different temporal scales
- Understand the underlying processes and their drivers
- Know the orders of magnitude for all variables in play
- Reporting on the measurement techniques used
- Putting into perspective and extrapolating the results obtained in relation to the literature
Prerequisite knowledge and skills
Planned learning activities and teaching methods
Each part will be presented ex-cathedra followed by numerical applications based on datasets obtained at our measurement sites.
Metrological aspects will be covered during field sessions (assembly of a micro-meteorological station).
Mode of delivery (face-to-face ; distance-learning)
- Lectures 12h - Practical works 48h - Seminaries 12h
Recommended or required readings
Lecture notes Proposed scientific papers
Assessment methods and criteria
The final rating will be determined on the basis of:
- the oral presentation, individually and in English, of a scientific article (1/3)
- the individual oral presentation of the analysis of a data set in the light of the concepts discussed in the course (2/3)
