The Earth's surface fluid mass redistribution, eg, groundwater depletion and severe drought,
causes the elastic surface deformation, which can be measured by global positioning …

We discuss a new method for approximately decorrelating and non-isotropically filtering the
monthly gravity fields provided by the gravity recovery and climate experiment (GRACE) twin …

The computerized ionospheric tomography is a method for imaging the Earth's ionosphere
using a sounding technique and computing the slant total electron content (STEC) values …

Spatial low‐pass filtering is necessary for processing the GRACE time‐variable gravity
(TVG) data which are otherwise plagued with short‐wavelength noises. Here we devise a …

Abstract In 2015, the International Association of Geodesy defined the International Height
Reference System (IHRS) as the conventional gravity field-related global height system. The …

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 …

The thin plate spline (TPS) is an interpolation approach that has been developed to
investigate a frequently occurring problem in geosciences: the modelling of scattered data …

The Gravity field and steady-state Ocean Circulation Explorer (GOCE) is the European
Space Agency's (ESA) satellite gravity mission to determine the Earth's mean gravity field …

We propose a methodology for local gravity field modelling from gravity data using spherical
radial basis functions. The methodology comprises two steps: in step 1, gravity data (gravity …

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 …
