Our research activities currently revolve around three main threads:
- the trace gas (CO2, CH4, N2O, COS, CO and several VOC), H2O and energy exchange of terrestrial and aquatic ecosystems as affected by land use and climate, and
- the applicability of the eddy covariance method in complex terrain, and
- the fusion of proximal sensing and eddy covariance flux measurements through a combination of inverse radiative transfer and footprint modeling.
To study these topics we use a blend of experimental methods and modelling approaches. Most of these are based on micrometeorological theory, but we also employ methods and use theory from the fields of plant ecology, ecophysiology, biochemistry and soil physics.
Our study sites are situated mainly in the Alps, where we study various terrestrial (mostly mountain grasslands) and aquatic ecosystems. We are responsible for running the long-term measurements at the FLUXNET (site code: AT-Neu) Neustift. Neustift is also an affiliated site in the PhenoCam network. Data from this site are freely available from the European Fluxes Database Cluster or upon request – see here for a list of publications in international, peer-reviewed publications that have made use of the data from Neustift. Within the frame of collaborations we also have conducted research at other sites, e.g. various desert ecosystems in Nevada/USA, Järvselja forest in Estonia or Castelporziano forest in Italy.
