Overview

The global terrestrial biosphere, i.e. the vegetation and soils, strongly reacts to variations in atmospheric conditions but also influences the atmosphere via exchange of matter and energy (e.g. trace gases, latent and sensible heat). These interactions occur on time-scales that range from seconds to millennia, and ascend from the molecular to the global spatial scale. They are mediated by the action of organisms which shape important biogeochemical and biogeophysical processes in their ecosystems, which in turn are forming landscapes, regions, and biomes. Hence we study the nature and the role of these interactions between the biosphere and the atmosphere, using a modelling approach, which integrates observations from organisms to global scale. This research should ultimately help understanding how the biosphere is reacting to and is exerting feedbacks on ongoing environmental change (e.g. changing water cycle, global warming, increasing atmospheric CO2 levels, and nitrogen deposition).
