Traces of impact craters in the geoid
Tectonophysics, 1992A well-known method for studying the impact craters on the Earth’s surface is gravity measurements. For practical studies, the gravity measured on the surface must first be reduced to a particular standard. In a simpIe procedure, after subtracting the latitude-dependent normal gravity, the topographic masses outside the geoid are either completely ...

How to get an European centimeter geoid (“astro-geological geoid”)
Physics and Chemistry of the Earth, 1996As shown by projects in hilly and alpine regions, astro-geoid solutions are more effective than gravimetry - but many countries do not utilize this fact. Both methods give accuracies of < 5cm/100km and are improved remarkably by subsurface density models (smoothing of the gravity field).

Using a ‘GPS/MSL Geoid’ to Test Geoid Models in the UK
2002GPS has been used to compute the height of mean sea level (MSL) above a reference ellipsoid at a network of 14 tide gauge sites, several hundred kilometres apart in the UK. The resultant ‘GPS/MSL geoid’ heights have then been compared to values taken from a global, an European and a national geoid model.

Comparison of Champ and GRACE geoid models with Croatian HRG2000 geoid
2004Latest Croatian geoid solution HRG2000 and CHAMP and GRACE global geopotential geoid models EIGEN-2 (CHAMP), EIGEN-01S (GRACE), GGM01S (GRACE) and GGM01C (GRACE) are compared. Orientation and long wave structure of the HRG2000 geoid is judged using CHAMP and GRACE models, while HRG2000 is used to judge the resolution of the global CHAMP and GRACE ...
