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 ...
Hydrogeology and water quality of wetlands in East Africa: case studies of a floodplain and a valley bottom wetland
(2017-10-10)
This thesis is embedded in the interdisciplinary BMBF-funded project “GlobE – Wetlands in East Africa”, which focuses on reconciling future food production in East African wetlands with the concurrent environmental protection ...
