Möglichkeiten der Nutzung kinematischer Satellitenbahnen zur Bestimmung des Gravitationsfeldes der Erde
(2010-06-04)
Die Extraktion von Schwerefeldinformation aus den Bahnverfolgungsdaten von Satelliten gehört zu den frühesten wissenschaftlichen Anwendungen der Weltraumtechnik. Die Ausrüstung von Satelliten mit GPS-Empfängern hat hier ...
Zur Bestimmung des cm-Geoids und dessen zeitlicher Variationen mit GRACE
(2007)
In dieser Arbeit wird eine Analysemethode unter Verwendung der dynamischen Methode zur Berechnung hochgenauer und hochauflösender Schwerefeldmodelle in Form von Kugelfunktionskoeffizienten auf der Grundlage der neuartigen ...
Large-scale mass redistribution in the Earth system from synergistic use of Swarm data
(2022-01-26)
Long and consistent time series of large-scale mass redistribution in the Earth system are important in many scientific research areas. The dedicated Gravity Recovery And Climate Experiment (GRACE) and Gravity Recovery And ...
Consistently closing global and regional sea level budgets
(2022-11-17)
Nowadays, human-induced climate change is the major driver of global and regional sea level change threatening the well-being and livelihoods of hundreds of millions of people living close to the coast. Consequently, ...
Thermosphere and radiation effects in forward and inverse non-gravitational force modelling
(2024-02-01)
Precise non-gravitational satellite force models are crucial for various space-based applications, thus contributing to a better understanding of the Earth system.

A global drought monitoring framework using GRACE/-FO data assimilation
(2024-12-09)
Extreme climate phenomena like droughts can lead to a shortage of available water resources that in turn can cause serious consequences such as famines. Monitoring of extremes is extremely important, and past research ...
Methods for assimilating remotely-sensed water storage changes into hydrological models
(2016-10-17)
Understanding physical processes within the water cycle is a challenging issue that requires merging information from various disciplines. The Gravity Recovery And Climate Experiment (GRACE) mission provides a unique ...
Gravity Field Refinement by Radial Basis Functions from In-situ Satellite Data
(2008)
In this thesis, an integrated approach is developed for the regional refinement of global gravity field solutions. The analysis concepts are tailored to the in-situ type character of the observations provided by the new ...
