Geopotential and geodynamic meters

Eos, Transactions American Geophysical Union, 1930
The work done in lifting a mass m, h units of length vertically, is given by the equationw = m g hprovided g, the local gravity‐acceleration, is constant over the distance in question. If g varies with height, and we know it does, then we must resort to integration and writew = m ∫ohg dhand express g as a function of h.

Geopotential resonances on Vanguard orbits

Journal of Geophysical Research, 1977
Since their establishment in 1959 the orbits of Vanguard 3 (1959-7A) and the Vanguard 2 rocket (1959-2B) have been slowly contracting through at least five strong resonances of eleventh order. Tracking with Baker-Nunn cameras and the U.S. Navy space surveillance (radio interferometer) system over a 14-year period has revealed resonant fluctuations on ...

Comparing different geopotential models in Spain

Marine Geodesy, 1994
This work focuses on some currently used high‐degree geopotential models that represent the gravity field in Spain. Six test areas of different topographic structures that cover the greatest part of the territory are selected to get information on the gravity field.

Efficient Satellite Based Geopotential Recovery

2007
This contribution aims at directing the attention towards the main inverse problem of geodesy, i.e. the recovery of the geopotential. At present, geodesy is in the favorable situation that dedicated satellite missions for gravity field recovery are already operational, providing globally distributed and high-resolution datasets to perform this task ...

Tailored Reference Geopotential Model for Africa

2015
In the framework of the African Geoid Project, the currently available gravity data set contains many significant gaps allover the continent. A possible way to fill in these gaps before the geoid computation process, is to use a global geopotential model which best fits the African gravity field.

Spheroidal and spherical geopotential approximations

Quarterly Journal of the Royal Meteorological Society, 2014
It is customary in atmospheric modelling to approximate the equi‐geopotential surfaces of apparent gravity as spheres, and to use spherical polar coordinates to represent the global atmosphere. However Earth's mean surface is more accurately approximated by a spheroid of revolution than by a sphere, and therefore the geopotential surfaces are better ...
