Geostatistical prediction of a local geometric geoid - kriging and cokriging with the use of EGM2008 geopotential model

Studia Geophysica Et Geodaetica, 2018
We investigate prediction abilities of different variants of kriging and different combinations of data in a local geometric (GNSS/leveling based) geoid modeling. In order to generate local geoid models, we have used GNSS/leveling data and EGM2008 geopotential model. EGM2008 has been used twofold.

A study of the EGM2008 model of Earth's gravitational field

Journal of Navigation, 2022
The Earth Gravity Model 2008 (EGM2008) is now some years old, and yet information on how to use it to calculate Earth's gravity remains obscure outside the field of geodesy.

A comparison of GOCE gravitational models with EGM2008

Journal of Geodynamics, 2014
Abstract Four new gravity field models from GOCE, two of them combined with GRACE, are compared here with EGM2008. The objectives are to look into the differences in consecutive ranges of the spherical harmonic expansion globally as well as in selected geographical regions and in the regions of the various data sources used for EGM2008.

Comparative analysis of free-fall acceleration differences in the EGM2008 model within geological interpretation

Modern achievements of geodesic science and industry
The study aims to analyze the differences in free‑fall acceleration (FFA) derived from various degrees/orders of calculation within the global EGM2008 model, followed by a comparison with geological data. Method. The realization of the objective involved

Evaluating the suitability of the EGM2008 geopotential model for the Korean peninsula using parallel computing on a diskless cluster

Computers and Geosciences, 2013
This paper describes a hybrid MPI/OpenMP approach to using diskless computing clusters to solve time-consuming problems related to ultra-high-degree and -order spherical harmonic analysis using the EGM2008 geopotential model with least-squares collocation to improve the accuracy of EGM2008-derived geoid heights.
