Abstract
The preservation of biodiversity is an increasingly important topic in European policy. Natural areas are constantly undergoing changes, mostly driven by socio-economic changes, and many of these changes lead to a reduction of the biodiversity. The following main research questions will be dealt with in this project:
- Which variables should be considered to be retrieved from hyperspectral and multispectral remote sensing, taking into account accuracy requirements of the ecological models?
- How is the uncertainty of remote sensing derived variables propagated into the ecological models?
- To what extent can uncertainty in model output be reduced by replacing present model input data by remote sensing derived variables?
- How can data derived from in situ (field) studies be extrapolated to scales that are relevant for ecological applications (regional, national and European scale)?
- How do differences in RS supported energy balance model formulations (i.e. SEBS and SEBAL) effect estimates of evapotranspiration.
- What is the dependence of the directionality of estimations of elements of the energy balance on different scales.
