Mission

The Model-Data Integration group explores strategies and develops methods to extract and transfer information from data to models, towards improving our understanding of ecosystem functioning and its representation in modeling structures. We aim at approaches which are robust enough to deal with inevitable deficiencies of data and models to represent complex systems. Within this context we test hypotheses about the dynamics of biogeochemical cycles in terrestrial ecosystems and their responses to environmental conditions. The two major challenges generally posed are the identification of plausible model structures, and the transformation of data properties ("patterns") into model properties ("parameters"). Considering "multiple-constraints" approaches and combining classical inverse parameter estimation techniques with machine learning approaches and modern time-series analysis has already proven a valuable approach for improving models.
