Earth tide correction
Earth 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. The largest body tide constituents are semi … See more The larger of the periodic gravitational forces is from the Moon but that of the Sun is also important. The images here show lunar tidal force when the Moon appears directly over 30° N (or 30° S). This pattern remains fixed with … See more The Earth tide encompasses the entire body of the Earth and is unhindered by the thin crust and land masses of the surface, on scales that … See more Seismologists have determined that microseismic events are correlated to tidal variations in Central Asia (north of the Himalayas); see: tidal triggering of earthquakes. … See more • Love numbers See more In coastal areas, because the ocean tide is quite out of step with the Earth tide, at high ocean tide there is an excess of water above what would be the gravitational equilibrium level, and therefore the adjacent ground falls in response to the resulting … See more Body tides also exist in other astronomical objects, such as planets and moons. In Earth's moon, body tides "vary by about ±0.1 m each … See more • McCully, James Greig, Beyond the Moon, A Conversational, Common Sense Guide to Understanding the Tides, World Scientific Publishing Co, Singapore, 2006. • Paul Melchior, … See more WebAug 9, 2024 · While the Scintrex CG-5 gravimeters can provide solid Earth-tide corrected measurements using the approach by Longman (1959), if needed gTOOLS can recalculate tides during data reduction. gTOOLS improves upon the tidal corrections employed by Scintrex by also a) computing the Moon and Sun longitudes with the original equations …
