Mean sea surface height

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 measurement methods, such as the buoy and ship survey, have a small cover area, sparse data, and high cost. Recently, the Global Navigation Satellite System-Reflectometry (GNSS … WebThe sea surface height relative to the geoid (the mean ocean surface of the Earth if the ocean is at rest) is derived from TOPEX/Poseidon, Envisat, Jason-1, and OSTM/Jason-2 …
