Surface fresh water is essential for life, yet we have surprisingly poor knowledge of the
spatial and temporal dynamics of surface freshwater discharge and changes in storage …

While multiple data sources have confirmed that Antarctica is losing ice at an accelerating
rate, different measurement techniques estimate the details of its geographically highly …

After about 6 years of GRACE (Gravity Recovery and Climate Experiment) satellite mission
operation, an unprecedented global data set on the spatio-temporal variations of the Earth's …

This article provides a survey on modern methods of regional gravity field modeling on the
sphere. Starting with the classical theory of spherical harmonics, we outline the transition …

An integrated approach was developed to assess the sustainability, origin, age, evolution,
and groundwater potential of large fossil aquifers using the Mega Aquifer System …

In this paper, we robustly analyze the noise reduction methods for processing spherical
harmonic (SH) coefficient data products collected by the Gravity Recovery and Climate …

We propose a class of spherical wavelet bases for the analysis of geophysical models and
for the tomographic inversion of global seismic data. Its multiresolution character allows for …

In this paper, three satellite derived precipitation datasets (TRMM, CMORPH, PERSIANN)
are used to drive the Hillslope River Routing (HRR) model in the Congo Basin. The …

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 …

This study presents a solution of the '1 cm Geoid Experiment'(Colorado Experiment) using
spherical radial basis functions (SRBFs). As the only group using SRBFs among the …
