WebSince 1993, satellite altimeters have provided continuous, near-global (± 66ºN) measurements of sea surface height. These measurements provide definitive estimates of global mean sea level rise during recent decades (~3.2 mm/year from 1993 to present) with much less uncertainty than the global rate derived from tide gauges. WebMean sea surface height (MSSH) is an important parameter, which plays an important role in the analysis of the geoid gap and the prediction of ocean dynamics. Traditional …

It includes an … WebSea Surface Height (SSH) is the height of the sea surface above a reference ellipsoid. This is the direct product of satellite altimetry. Sea surface height values are provided along …
WebThe satellites measure the height of the sea surface with an accuracy of about 3 centimeters (just over 1 inch) relative to the center of the Earth, and they collect data over nearly all of Earth's ice-free ocean every 10 days. WebAug 10, 2024 · Global mean sea level has risen 101 millimeters (3.98 inches) since 1992, and it continues to do so at 3.9 mm (0.15 inches) per year. ... From this, scientists derive the height of the sea surface directly underneath the satellite.
