The topics of this research field aim on the improvement of understanding the dynamic processes and thier interactions within the components of the system Earth observed by geodetic measurement techniques. Due to the close connection to other geoscience disciplines, such as geophysics, meteorology, oceanography or hydrolgy, complementary data from other sensors are integrated into the modeling process. The combination of all data allows for a reliable estimation of information on the dynamic processes, which are of great importance for monitoring climate change. The results will be delivered to other scientific disciplines and especially to the public in order to provide competent knowledge for discussions on global change. 

Usually the geometric and gravimetric space-geodetic observations provide precise and high-resolution integral information to different balances within the system Earth. In this research field specific processes will be investigated in order (1) to separate the measured integral signals into the individual contributions, (2) to access the accuracy of single process parameters and (3) to close balances as good as possible. These tasks will be solved by introducing mathematical and (geo-)physical models of dynamic processes within the system components. Finally, we aim on a modelling procedure for the Earth system components which is realistic and as complete as possible. To achieve this goal we currently work on the tasks listed below.

 

• Analysis and Validation of geophysical Earth system models from Earth rotation variations
• Separation of mass signals from gravimetric and geometric observations
• Determination and analysis of troposphere parameters
• Multi-dimensional ionosphere model from the combination of space-geodetic observation techniques
• Empirical modeling and analysis of ocean tides
• Dynamic Ocean Topography and Mass Transport
• Registration and analyis of the Earth's free oscillations with the 30m vertical pendulum in the salt mine of Berchtesgaden
• Separation of water storage compartments of the continental hydrology from gravity and remote sensing data
