Extreme event impacts

Background The gross primary production (GPP) of an ecosystem, that is, the carbon it assimilates via photosynthesis, differs strongly from one year to the next. This variability between years is called the interannual variability (IAV) of GPP and the reasons for why GPP can change substantially from year to year are unclear.

Supervision: Prof. Benjamin Stocker Background Exchange fluxes of water vapour between ecosystems and the atmosphere are commonly measured using eddy-covariance technique. This gives information about how much water is transpired by plants and evaporated from soil and plant surfaces.

Supervision: Dr. Laura Marques and Prof. Benjamin Stocker Background Climate warming is driving an advance of leaf unfolding in trees, promoting longer growing seasons. However, the advance of the start-of-the-season (SOS) can induce false springs, i.
