Climate- and Human-Induced Vegetation Changes in Northwestern Turkey and the Southern Levant since the Last Glacial
(2017-04-20)
Northwestern Turkey and the southern Levant are key regions for studying vegetation and climate developments during migration phases of modern humans and the origin and expansion of agriculture. Both regions have a long ...
Palaeoclimate Reconstruction in the Levant and on the Balkans
(2017-08-25)
For an understanding of the climate system’s variability, knowledge of the past climate is essential. Continuous observations are not available for longer than the last 100 years, a period that is insufficient to understand ...
Biogeomorphic dynamics in the Turtmann glacier forefield, Switzerland
(2017-05-19)
Worldwide, glacier retreat enlarges glacier foreland areas, which are characterized by pronounced geomorphic and ecologic dynamics. Feedbacks between these dynamics are believed to drive glacier foreland landscape development, ...
Multiseasonal Remote Sensing of Vegetation with One-Class Classification – Possibilities and Limitations in Detecting Habitats of Nature Conservation Value
(2017-07-03)
Mapping of habitats relevant for nature conservation often involves the identification of patches of target habitats in a complex mosaic of vegetation types extraneous for conservation planning. In field surveys, this is ...
Improvements and application of the STatistical Analogue Resampling Scheme STARS
(2017-07-03)
Basically, there are two approaches to downscale climate simulations from global climate models to a regional scale: dynamical and statistical downscaling. This thesis focuses on a statistical method – the Statistical ...
Monitoring structural and physiological properties of crop roots using spectral electrical impedance tomography
(2017-06-09)
Non- or minimally invasive methods are urgently needed to characterize and monitor crop root systems, both on the laboratory and the field scale. Traditional research methods still overwhelmingly rely on manual labor, which ...
Verification and post-processing of ensemble weather forecasts for renewable energy applications
(2017-07-10)
The energy transition taking place in Germany encourages a large scale penetration of weather-dependent energy sources into the power grid. The grid integration of intermittent sources increases the need for balancing ...
3D Radar reflectivity assimilation with an ensemble Kalman filter on the convective scale
(2017-03-10)
Atmospheric processes are governed by strongly nonlinear dynamics, and predicting convective events is a challenging task. In numerical weather prediction (NWP), an accurate description of the current state of the atmosphere ...
Transformative Adaptation and Natural Resource Management Interventions in North Eastern Ethiopia
(2017-01-04)
This study is motivated by the observation that adaptation to climate change is often presented as a technical problem that requires only engineering and technological solutions. What is missing from current adaptation ...
Numerical modeling of electromagnetic coupling effects for phase correction in borehole EIT measurements
(2017-04-25)
Spectral Electrical Impedance Tomography (EIT) allows obtaining images of the complex electrical conductivity for a broad frequency range (mHz to kHz). It has recently received increased interest in the field of near-surface ...
