Weidenbrunnen_Haupttum  EGER_Turb_Tower_vonunten

Investigation of the energy and matter exchange within a forest ecosystem with a focus on turbulent structures and interactions between forest, atmosphere and soil. The station has a 32 m high scaffold tower for micrometeorological profile measurements and air-chemical measurements (only within campaigns) and since 2007 a 36 m high slim tower for turbulence studies.

Measurements of the carbon dioxide fluxes with the eddy-covariance method started in 1996 (Station GE1 of the EUROFLUX-classification) on an initiative of Prof's. Schulze and Tenhunen. Since that time the station is part of the FLUXNET network.
