In the joint effort of EGER we will study the diurnal cycles of energy, water, and trace ubstances in the soil–vegetation–boundary-layer system. In the second phase of the EGER roject, because of the wind throw by “Kyrill” these investigations are related to disturbed cosystems. Current landscape studies suffer poor description of scale transitions and nteractions especially in the case of such heterogeneities. Therefore our former research goal was modified and directly related to this important problem for which the Waldstein area s now an ideal natural laboratory. As one consequence we gain additional knowledge regarding the spatial patterns of the investigated biological, chemical, and physical arameters.

This allows an improved understanding of exchange processes and budgets. The proposed ethodology is innovative in the sense that it uses a multiscale approach that combines bservations in the soil–vegetation–boundary-layer system with adequate modelling. This is hallenging because the study area is ideal for micrometeorological experiments and
adequate modelling with Large-Eddy-Simulation.

On the international level, our research tackles with the key issues (foci 1 & 4) of the IGBP and-atmosphere core project iLEAPS (Integrated Land-Ecosystem-Atmosphere Processes tudy, see http://www.atm.helsinki.fi/ILEAPS).
