Example of the on-line visualisation service: geoid hights of the model EIGEN-6C2 as illuminated projection on a sphere (GFZ) Example from the animation of the monthly models: geoid differences of the model for November 2010 to the mean model EIGN-6S.
Visualization of Gravity Field Models and their Differences
The Geoid undulations are multiplied with a so-called radial 'boost factor' (initial value: b = 10,000) to make them visible. You can select another Functional, gravity Model and Subtrahend model (to display model differences).

The updated GFZ Grace Gravity (G3) Browser is available on ICGEM. It computes time series of equivalent water height and gives users the opportunity to compare different series. ICGEM is one of five services coordinated by the International Gravity Field Service (IGFS) of the International Association of Geodesy (IAG) .
Integrative gravity and isostatic models: GFZ - gfz-potsdam.de
We use a joint analysis of the gravity field/geoid with seismic (P-, S-velocities), surface topography, heat flow and other geophysical and mineral-physics data, which are integrated into a comprehensive global model of the crust and upper mantle.

Combination of spaceborne, airborne and in-situ gravity measurements in support of Arctic sea ice thickness mapping.
Terrestrial and Airborne Gravimetry - gfz-potsdam.de
The GFZ has recently acquired a new iCORUS strapdown gravimeter from the manufacturer iMAR Navigation & Control. The iCORUS is currently used together with the Chekan gravimeter in ship gravimetry on the North Sea. The aim of this activity is determination of …

Dec 11, 2023 · ICGEM evaluates the static gravity field models w.r.t. GNSS/levelling derived geoid undulations (http://icgem.gfz-potsdam.de/tom_gpslev) and in the spectral domain w.r.t. already reliable models (http://icgem.gfz-potsdam.de/evalm).
The South American gravimetric geoid: GEOID2021
The South American gravimetric geoid model, named GEOID2021, was computed thanks to a collaboration of several institutions, companies and universities of South America. The model covers the area between 15°N and 60°S in latitude and 100°W and 30°W in longitude, with a grid resolution of 5' x 5'.
Establishment of the global geoid model 2022 (GGM2022)
Abstract: Global geoid plays key role in world height system. Here we report the 5’ times 5’ global geoid model 2022 (GGM2022) established based on the shallow layer method (Shen method).
ICGEM continues to evaluate the static gravity field models w.r.t. GNSS/levelling derived geoid undulations (see the list in Fig. 5) and in the spectral domain w.r.t. already reliable models (see Figs. 6).
