Gravity Field, Time Variations from Surface Measurements

Abstract

Earth's dynamic gravity field; Temporal variations of the Earth's gravity Definition Temporal gravity changes Variation of Earth's gravity field with time due to various tidal, oceanic, atmospheric, hydrological, glaciological, volcanic, seismic, and tectonic processes. Tidal gravity changes The periodic variation of gravity field due to the attraction of Sun and Moon. Non-tidal gravity changes Gravity changes unrelated to the attraction of Sun and Moon.
