GOCE gravity models and gravity gradient assessment [PDF]
The GOCE (Gravity field and steady-state Ocean Circulation Explorer) mission launched on 17 March 2009 provides for the first time Satellite Gravity Gradiometer (SGG) data. It is designed to recover the Earth gravity anomaly field with an accuracy of better than 1 to 2 mGal with a spatial resolution of 100 km or less.

Gravity gradient noise from asteroids [PDF]
The gravitational coupling of nearby massive bodies to test masses in a gravitational wave (GW) detector cannot be shielded, and gives rise to 'gravity gradient noise' (GGN) in the detector. In this paper we show that for any GW detector using local test masses in the Inner Solar System, the GGN from the motion of the field of $\sim 10^5$ Inner Solar ...

Ocean dynamic equations with the real gravity
Two different treatments in ocean dynamics are found between the gravity and pressure gradient force. Vertical component is 5–6 orders of magnitude larger than horizontal components for the pressure gradient force in large-scale motion, and for the ...
