Prior to the launch of Topex/Poseidon, knowledge of tides over the global ocean was based primarily on hydrodynamical models. The accuracies of these models were limited by some uncertainties and were constrained by empirically determined ocean tides from a worldwide network of coastal and inland tide gauges and bottom pressure gauges. Models for the correction of the body tides exist, but since there is still no global ocean tidal model available that also fits all the shelf tides further gravity measurements are needed.

Seas and discussed the problem how to improve a global ocean tide model at a regional scale. In the work of Fang et al. (), harmonic analysis of 10 years of T/P along-track altimetry was performed to derive the semidiurnal, diurnal, long-period and quarter-diurnal tides in . ocean tide model. Tidal parameters from 56 coastal tide-gauge stations around the Mediterranean for eight principal constituents: M2, S2, N2, K2, K1, O1, P1 and Q1 and from 20 stations for M2, S2, K1, O1 are included in the model. TOPEX/Poseidon data with all corrections applied except for the ocean tides and bathymetry from TOPO were usedCited by:
Launched in , TOPEX/Poseidon is a joint venture between CNES and NASA that measured ocean surface topography to an accuracy of cm, enabled scientists to forecast the El Niño, and improved understanding of ocean circulation and its effect of global climate.

D Ray. Goddard Ocean Tide model GOT is a new solution for the amplitudes and phases of the global oceanic tides, based on over six years of sea-surface height measurements by the TOPEX/POSEIDON satellite altimeter.
The ocean tide model was derived from the combined use of ERS 1 and TOPEX/POSEIDON data by using a modified orthotide formulation that simultaneously solves for all diurnal and semidiurnal constituents as well as the annual by: The ocean tide model was derived from the combined use of ERS 1 and TOPEX/POSEIDON data by using a modified orthotide formulation that simultaneously solves for all diurnal and semidiurnal constituents as well as the annual by: A global ocean tide model (NAOb model) representing major 16 constituents with a spatial resolution of ° has been estimated by assimilating about 5 years of TOPEX/POSEIDON altimeter data into barotropic hydrodynamical by: mate change.
TOPEX/Poseidon (T/P) is the ﬁrst global system of satellite altimetry that was explicitly designed to study ocean dynamics by accurately measuring sea surface height relative to the center of the earth (Fu et al.
In order to decipher the low-amplitude (of the order of several centimeters) changes in sea level, it is ﬁrst. Altimetric data from the TOPEX/POSEIDON mission will be used for stu- dies of global ocean circulation and marine geophysics.
However, it is first necessary to remove the ocean tides, which are aliased in the raw Size: 3MB. Measurements from the TOPEX/Poseidon and Jason series of satellite radar altimeters have been used to estimate global mean sea level height.
These data are available for October, to present. Tide gauge sea level data have complementary strengths and weaknesses. Altimetric data from the TOPEX/POSEIDON mission will be used for studies of global ocean circulation and marine geophysics.
However, it is first necessary to remove the ocean tides, which are aliased in the raw data. The tides are constrained by two distinct types of information: the hydrodynamic equations which the tidal fields of elevations and velocities must satisfy, and direct observational data from tide gauges and satellite by: Cotidal Charts near Hawaii Derived from TOPEX/Poseidon Altimetry Data LI-LI FAN,BIN WANG, AND XIAN-QING LV teristics of ocean tides and build either a global or re-gional tidal model.
The ﬁrst application of T/Paltimeter data covering about 7 months was carried out to derive ocean tides in the Asian semi-enclosed sea by Mazzega and Berge. The great majority of the ocean tide models derived from altimetry are empirical and fit a certain model representation through the altimeter observations mostly using some kind of harmonic or response analysis.
Recently, altimeter data from GEOSAT, ERS-1, and TOPEX/POSEIDON, have successfully been used for ocean tidal by: 5. Tidal constants are computed from TOPEX/Poseidon sea level data in the northeast Pacific Ocean for the period of September December The method used is harmonic analysis.

Global ocean tide model results were derived from a blend of solving the hydrodynamic equations and assimilating altimeter SSH data, primarily from the joint TOPEX/Poseidon (T/P) mission.
Most models have a greater bias towards T/P assimilation rather than full reliance on solving the governing hydrodynamic equations. Reasonable results have. A Global Ocean Tide Model from TOPEX/POSEIDON Altimetry: GOT (NASA/TM, Goddard Space Flight Center, Greenbelt, Maryland ).
