Topographic Effects in Geoid Determinations
Geosciences, 2018 Traditionally, geoid determination is applied by Stokes’ formula with gravity anomalies after removal of the attraction of the topography by a simple or refined Bouguer correction, and restoration of topography by the primary indirect topographic ...

Backwater Effects From River Ice Jams Observed With SWOT Pixel Cloud Data
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract This study examines the backwater effects from ice jams in Arctic rivers using the Surface Water and Ocean Topography (SWOT) satellite. Ice jams occur when chunks of ice accumulate and obstruct the river flow, causing rapid water level rises and flooding.

Influencing factors on the accuracy of local geoid model
Geodesy and Geodynamics, 2019 Different modification methods and software programs were developed to obtain accurate local geoid models in the past two decades. The quantitative effect of the main factors on the accuracy of local geoid modeling is still ambiguous and has not been ...

Impact of datum transformation on local variations of geometric geoid in Niger
Geodesy and Cartography, 2017 In this study, we have conducted an investigation on the impact of the coordinates’ transformation on local variations of geometric geoid. The study area is limited by 1°43′12″ to 4°00′37″ East and 13°01′57″ to 14°31′20″ North in the southwest of the ...

Self‐Affine Scaling of Earth's Islands
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Earth's relief is approximately self‐affine, meaning a zoom‐in on a small region looks statistically similar to a large region upon rescaling. Fractional Brownian surfaces give an idealized self‐affine model of Earth's relief with one parameter, the Hurst exponent H $H$, characterizing the roughness of the surface.

A benchmark study on mantle convection in a 3-D spherical shell using CitcomS [PDF]
, 2008 As high-performance computing facilities and sophisticated modeling software become available, modeling mantle convection in a three-dimensional (3-D) spherical shell geometry with realistic physical parameters and processes becomes increasingly feasible.
