The laboratory of Land-Atmosphere Interaction conducts various field and laboratory studies to understand complex carbon dynamics in terrestrial ecosystem and to predict the multiple impacts of climate change on ecosystem functions.

1) Ecosystem carbon cycle in the High Arctic.

2) Vegetation dynamics, energy, water and carbon exchange between atmosphere and forest ecosystems.

3) Role of biological components in the carbon dynamics along river basin.
