WebThe surface of the Earth is described as near as possible by a spheroid, i.e. a 3D shape. To all intents and purposes for this discussion of using RTK for tide correction we consider just the one ellipsoid (meridian) on the Earth’s surface where the User is located. The ellipsoid is a single “ring” whereas the spheroid is the 3D shape.

WebThe lunar tidal effect is calculated in an analogous way. Again, one has to realize that Earth is in a free fall towards the Earth-Moon center of mass. The difference between the Moon’s pull on a unit mass at the center of Earth and at the closest/farthest point on Earth is ∆ a a R d g m m m = = ×-2 113 10 7.

The nominal values of Love and Shida numbers are used in common for all tidal components and all stations. (1) Displacement caused by degree - 2 tides
WebOct 20, 2005 · The tidal deformation of the solid earth is superimposed by the loading effect caused by the ocean tides. There are two contributions: the attraction of the moving water masses and the deformation of the crust due to the water load. Thus, the elasticity of the local crust-mantle structure controls the response.
WebDec 20, 2024 · Earth and ocean tides. The solid Earth responds to the pull of the Sun and the Moon just like the oceans, but movements are much smaller. The Sun and the Moon also pull on the gravimeter and its parts. These effects are large enough to affect gravity readings .
