WebEarth tide (also known as solid Earth tide, crustal tide, body tide, bodily tide or land tide) is the displacement of the solid earth's surface caused by the gravity of the Moon and Sun. Its main component has meter-level amplitude at periods of about 12 hours and longer. WebA correction made in gravity observations to remove the effect of the earth's tides.

WebThe Earth tide may cause changes of 2.4 µm/s 2 in the worst case, but it has period of about 12.5 hours; it is well approximated as a straight line over intervals of 1 to 2 hours, or it can be calculated and removed. Drift is also well eliminated by linear correction. Webtides and solid Earth tides. Ocean tide corrections are computed from a model that defines the tidal surface relative to a mean surface associated with the deformed solid Earth. The solid Earth tide correction reflects the vertical displacement of the crust of the Earth with respect to the ellipsoid due to the attraction of the Sun and Moon.

WebThus, migrating solar tides have the same local time variation at all longitudes. If n=1 and s=−1, the tide is diurnal and moves or migrates westward in longitude with the apparent motion of the Sun from the perspective of a ground-based observer.Further, c ph =−(2π/24)h −1.Similarly, if n=2 and s=−2, then the wave is a migrating semidiurnal tide.
