The Laegern site (47.48N, 8.40E) is composed of
a managed mixed deciduous mountain forest, dominated by Common beech (Fagus sylvatica) and Norway spruce (Picea abies). It is located on the
south-facing slope of the Laegern mountain northwest of Zurich (CH) at about
680 m asl. (Etzold et al., 2010). The site serves as a supersite for various
activities and forms part of CarboEurope (Eddy flux measurements), AERONET,
NABEL (Swiss air quality network), Pyrogenic carbon studies network and the
European Space Agency project 3D Vegetation Lab (Morsdorf et al., 2011).
