Aims:

  • to reconstruct the temporal and spatial variability of the climate of the past utilizing multi-parameter tree ring analysis
  • to assess and verify the causes of climate change and its impact on woody plants

Tasks:

  • quantitative analysis of the climate-signal transfer from atmosphere through soil and leaf into the wood of tree rings (Monitoring, calibration and verification of tree ring parameters vs. instrumental data)
  • to establish multi-centennial to millennium long time series of tree-ring parameters (ring width, cellstructure parameters, stable isotope ratios) for networks of sites from selected regions of the earth
  • comparative study of time series of climate proxies from different geo-archives (varved sediments, spelethemes, corals etc.)

Facilities

Up-to-date equipment of the dendrology laboratory of section 5.2 allows high precision and accuracy of sample preparation and analysis, as well as best possible automation.
