WebA Correction Strategy for Instrument Drift and Tides. The result of the drift and the tidal portions of our gravity observations is that repeated observations at one location yield different values for the gravitational acceleration. The key to making effective corrections for these factors is to note that both alter the observed gravity field as slowly varying … WebFigure 1 illustrates an example of the effect of the Solid Tides correction.

WebEarth tide, deformation of the solid Earth as it rotates within the gravitational fields of the Sun and Moon. Earth tides are similar to ocean tides. The Earth deforms because it has a certain degree of elasticity; were it perfectly rigid, there would be no Earth tides.

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.
