A sensitivity study of decadal climate prediction to aerosol variability using ECHAM6-HAM (GCM)
(2016-12-22)
The influence of aerosols on climate is an important but still highly uncertain aspect in climate research. Using the atmospheric general circulation model ECHAM6-HAM the objective of this study is to quantify the aerosol ...
Agricultural transformation and indigenous communities: A case study of the Soliga Communities in the montane forests, Southern India
(2016-09-15)
Rural indigenous communities (Adivasi) represent some of the most marginalized and poorest people in India. Their socio-economic and cultural livelihoods are subject to rapid change. Introduction of commercial agriculture ...
3D hydrological simulation of a forested headwater catchment: Spatio-temporal validation and scale dependent parameterization
(2016-09-30)
Soil moisture plays a key role in the water and energy balance in soil, vegetation and atmosphere systems. There is a grand need to increase global-scale hyper-resolution water-energy-biogeochemistry land surface modelling ...
Statistical relational learning of semantic models and grammar rules for 3D building reconstruction from 3D point clouds
(2016-11-04)
Formal grammars are well suited for the estimation of models with an a-priori unknown number of parameters such as buildings and have proven their worth for 3D modeling and reconstruction of cities. However, the generation ...
Interlinkages of Land Degradation, Marginality and Land Use Cover Change in Kenya: Development of an interdisciplinary framework using remote sensing and GIS
(2015-12-01)
Land degradation (LD) is a global problem affecting and being affected by socio-ecological systems. In this thesis the interlinkages of LD, marginality and land use cover change (LUCC) in Kenya based on remote sensing and ...
Streamwater transit time distributions at the catchment scale: constraining uncertainties through identification of spatio-temporal controls
(2016-04-08)
Precipitation water traveling through a catchment takes faster and slower flow paths to reach the outlet. The knowledge about the distribution of relevant flow paths in a catchment and their respective transit times of ...
Interpretation of Aerial Images with Learned Graphical Models
(2016-02-16)
In this thesis we present a new approach for image interpretation of aerial images using learned graphical models.
The approach uses a region based hierarchical feature adjacency graph. This contains homogeneous ...

A high-resolution regional reanalysis for Europe and Germany: Creation and Verification with a special focus on the moisture budget
(2015-10-22)
Atmospheric reanalyses represent a state-of-the-art description of the Earth‘s atmospheric state over the past years or decades. They are comprised of a numerical model for the solution of the equations of motion describing ...
Influence of Subsurface Hydrodynamics on the Lower Atmosphere at the Catchment Scale
(2015-12-23)
Processes (e.g., groundwater flow, evapotranspiration, precipitation) in different compartments of the hydrological cycle (e.g., subsurface, land surface, and atmosphere) show characteristic variability at different ......
Die Prozesse (z.B. Grundwasserströmung, Evapotranspiration, Niederschlag), die in den verschiedenen Kompartimenten des hydrologischen Kreislaufs (z.B. Boden, Landoberfläche und Atmosphäre) stattfinden, zeigen eine ......

The role of soil heterogeneity on field scale evapotranspiration: 3D integrative modelling and upscaling of root water uptake
(2015-09-24)
Background and Motivation: Hydrological models mainly rely on empirical functions to describe root water uptake. However, in case of water limitation due to either scarce or heterogeneously distributed soil water, plants ......
