Learning unit contents

This course covers the exchanges (fluxes) of energy, CO2, H2O, CH4 and N2O between the terrestrial ecosystems and the atmosphere. More precisely the following themes are addressed :

Theme 0 : Flux determinants

Theme 1 : Energy balance

Theme 2 : Atmospheric turbulent transport

Thème 3 : Carbone balance

Theme 4 : Water balance

Theme 5 : Nitrogen balance

Theme 6 : Methodology of flux measurement

Theme 7 : Use of stable isotopes of carbon, oxygen, hydrogen and nitrogen

The  order of magnitude of the different fluxes at the ecosystem-atmosphere interface and reservoirs in these cycles, the flux determinants and their measuring techniques are presented in the lectures and tutorials. This implies that several transversal themes are addressed and used: ecophysiology; soil physics, chemistry and biology; hydrology, micrometeorology;...

Learning outcomes of the learning unit

After completing the course the student is expected to be able to:

  • identify major plant controls on energy, water and trace gas flux exchanges with the soil and the atmosphere
  • understand how climate and ecosystem management impact these exchanges
  • Understand the requirements, strengths and limitations of ecosystem/atmosphere and trace gas flux measurement methods at spatial scales from leaves to the whole canopy.
  • Implement the most widely used of these flux measurement methods
  • Examine critically peer-reviewed publications in the domain of plant/ecosystem/climate exchanges
  • Better understand the terrestrial ecosystem roles in the climate system and, conversely, the impact of climate on these ecosystems, especially in terms of productivity and vulnerability.
Soft skills linked to team work and written and spoken English language will be developed through practical works, scientific publication analysis and oral presentations.

Prerequisite knowledge and skills

Planned learning activities and teaching methods

The students


  • work on a data set including few fluxes and reservoirs mentionned above, with the aim to analyse the behavior of the cycles for one particular ecosystem
  • set up some measurement devices to quantify some of the fluxes and reservoirs mentionned above (Eddy Covariance, meteorological measurements)

Mode of delivery (face to face, distance learning, hybrid learning)

Face-to-face course


Additional information:

- Lectures 30h
- Practical works 27h

In the event of an orange code: Theory will be given in distance learning courses and practical work in the classroom (computer room, field lab).

In case of code red: Theory and computer-based practical work will be given in distance learning and field labs will be cancelled.
