Signals of Climate Variability in Continental Hydrology


The latest IPCC assessment report identified once more the land hydrology as the most uncertain component of the global water cycle. Variations of continental water storage occur in several hydrological compartments such as groundwater, soil moisture, surface water and snow. These storage variations and related changes of mass and surface water extensions map into a considerable number of different space based or in-situ observation systems such as the GRACE gravity field mission, radar and laser altimeter systems, radiometers, optical sensors, synthetic aperture radar, and in-situ river gauges.

The present project aims to perform a multi-sensor approach in order to detect, separate and balance individual contributions to continental water storage variations for selected large river basins. In addition there will be the analysis of balance inconsistencies with respect to non-hydrological mass changes (e.g. due to forest fires and erosion). A specific focus of the study shall be placed on the analysis of climate signals. The study exploits the synergies of various observation systems and combines their output with hydrological simulation models. The project will be carried out within a largely interdisciplinary group of networking scientists and PhD students from space engineering (ESPACE), geodesy, hydrology and climate research. It will provide significant new and valuable insights into hydrological processes and the impacts of climate change on the global water cycle.
