Recent results based on continuous GPS observations of the GIA process in Fennoscandia from BIFROST

M Lidberg, JM Johansson, HG Scherneck… - Journal of …, 2010 - Elsevier
We present the latest 3D velocity field of the Fennoscandian glacial isostatic adjustment

A general model for modifying Stokes' formula and its least-squares solution

LE Sjöberg - Journal of geodesy, 2003 - Springer
Today the combination of Stokes' formula and an Earth gravity model (EGM) for geoid
determination is a standard procedure. However, the method of modifying Stokes' formula …

A computational scheme to model the geoid by the modified Stokes formula without gravity reductions

LE Sjöberg - Journal of geodesy, 2003 - Springer
In a modern application of Stokes' formula for geoid determination, regional terrestrial gravity
is combined with long-wavelength gravity information supplied by an Earth gravity model …

Deterministic, stochastic, hybrid and band-limited modifications of Hotine's integral

WE Featherstone - Journal of Geodesy, 2013 - Springer
Abstract Global Navigation Satellite System positioning of gravity surveys permits geoid
computation via Hotine's integral. A suite of modifications is presented so that the user can …

A new gravimetric geoid model for Sudan using the KTH method

A Abdalla, D Fairhead - Journal of African earth sciences, 2011 - Elsevier
Sudan is characterized by vast area with flat terrains in most of the country's regions and
therefore the existence of a high-resolution geoid model is considered very important …

A Meissl-modified Vaníček and Kleusberg kernel to reduce the truncation error in gravimetric geoid computations

WE Featherstone, JD Evans, JG Olliver - Journal of geodesy, 1998 - Springer
A deterministic modification of Stokes's integration kernel is presented which reduces the
truncation error when regional gravity data are used in conjunction with a global …

Reformulation of Stokes's theory for higher than second‐degree reference field and modification of integration kernels

P Vaníček, LE Sjöberg - Journal of Geophysical Research …, 1991 - Wiley Online Library
An argument is put forward in favor of using a model gravity field of a degree and order
higher than 2 as a reference in gravity field studies. Stokes's approach to the evaluation of …

Performance of three types of Stokes's kernel in the combined solution for the geoid

P Vaníček, WE Featherstone - Journal of Geodesy, 1998 - Springer
When regional gravity data are used to compute a gravimetric geoid in conjunction with a
geopotential model, it is sometimes implied that the terrestrial gravity data correct any …

The 5 mm geoid model for Estonia computed by the least squares modified Stokes's formula

A Ellmann, S Märdla, T Oja - Survey review, 2020 - Taylor & Francis
Computational stages of a new high-resolution 5 mm quasigeoid model for Estonia are
explained. Certain requirements for the quality and coverage of gravity data in the context of …

Effect of the SRTM global DEM on the determination of a high-resolution geoid model: a case study in Iran

R Kiamehr, LE Sjöberg - Journal of Geodesy, 2005 - Springer
Any errors in digital elevation models (DEMs) will introduce errors directly in gravity
anomalies and geoid models when used in interpolating Bouguer gravity anomalies. Errors …
