  author={C. Le Provost and A. Bennett and D. Cartwright},
  pages={639 - 642}
Comparisons of TOPEX/POSEIDON tidal solutions derived from the data of the first year of this altimetric mission with the best previous models and with in situ data show very substantial improvements. Typically, the gain in accuracy for the major lunar tidal component M2 is 30 percent in root-mean-square differences with reference to a standard ground truth data set from 78 stations distributed over the world ocean. This is a major step, obtained because of the high quality of these altimetric… Expand
Error spectrum for the global M2 ocean tide
The most accurate determinations of the global ocean tides are currently based on altimeter measurements made by the Topex/Poseidon satellite. The error spectrum corresponding to the M2 tidalExpand
NLOADF: A program for computing ocean‐tide loading
The loading of the Earth by the ocean tides produces several kinds of signals which can be measured by geodetic technique. In order to compute these most accurately, a combination of global and localExpand
Accuracy assessment of recent ocean tide models
Over 20 global ocean tide models have been developed since 1994, primarily as a consequence of analysis of the precise altimetric measurements from TOPEX/POSEIDON and as a result of parallelExpand
Diurnal/semidiurnal oceanic tidal angular momentum: Topex/Poseidon Models in comparison with Earth's rotation rate
The oceanic tidal angular momentum (OTAM) has been demonstrated to be the primary cause for the diurnal and semidiurnal variations in the Earth's rotational rate, or AUT1. Three ocean tide modelsExpand
Intercomparison of recent ocean tide models
One of the tremendous achievements of the TOPEX/POSEIDON (T/P) satellite mission is the release of 12 new global ocean tide models during 1994. Virtually all of these models are based on theExpand
Inversion of oceanic tidal currents from measured elevations
Abstract The problem of deducing tidal current velocities from measured tidal elevations is considered. Emphasis is given to global scales for which accurate cotidal charts based on satelliteExpand
On the statistical stability of the M2 barotropic and baroclinic tidal characteristics from along‐track TOPEX/Poseidon satellite altimetry analysis
An along-track analysis of 7 years of TOPEX/Poseidon (T/P) data has been performed on the global ocean over the period 1993-1999. Such long time series allow us to determine the semidiurnal tidalExpand
The Circulation and its Variability of the South Atlantic Ocean: First Results From the TOPEX/POSEIDON Mission
The sea surface height observations made by the radar altimetry system aboard the TOPEX/POSEIDON satellite, the first satellite dedicated to the study of the global ocean circulation, were used toExpand
Surface manifestation of internal tides generated near Hawaii
Analysis of Topex/Poseidon satellite altimetry reveals short-wavelength fluctuations in the ocean surface tide that are attributable to internal tides. A significant fraction of the semidiurnalExpand
Geometrical determination of the Love Number h2 at four tidal frequencies
The Love number h2 is determined at the M2, N2, O1, and K1 frequencies by combining satellite altimetry with in situ ocean tidal measurements. Topex/Poseidon altimetry is used to measure the (ocean +Expand


TOPEX/POSEIDON tides estimated using a global inverse model
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 aliasedExpand
Extraction of the M2 ocean tide from SEASAT altimeter data
Summary. Three complementary methods for the extraction of the M2 ocean tide using SEASAT altimetry are presented and compared. The first method (that developed by Cartwright & Alcock), whichExpand
A preliminary tidal analysis of TOPEX/POSEIDON altimetry
Approximately 12 months of data from the TOPEX/POSEIDON satellite altimeter mission are analyzed for the major short-period oceanic tides. A harmonic analysis is performed on data captured withinExpand
Observations of the Mf ocean tide from Geosat altimetry
Zonal averages of the 13.66-day Mf tide are derived from one year of Geosat altimetry records. The orbit errors are reduced by 1/revolution corrections taken over long (several day) arcs. TheExpand
The M2 oceanic tide recovered from Seasat altimetry in the Indian Ocean
Seasat altimeter data, which provide measurements of the instantaneous ocean level, are used here to create a model of the M2 oceanic tide in the Indian Ocean. This approach avoids the assumptionsExpand
Determination of ocean tides from the first year of TOPEX/POSEIDON altimeter measurements
An improved geocentric global ocean tide model has been determined using 1 year of TOPEX/POSEIDON altimeter measurements to provide corrections to the Cartwright and Ray (1991) model (CR91). TheExpand
Energetics of global ocean tides from Geosat altimetry
The authors' global ocean tide maps derived from Geosat altimetry are here improved in quality and coverage; they compare favorably with ground truth data at about the same rms level as Schwiderski'sExpand
Modeling ocean tides with and without assimilating data
When reviewing the application of semiempirical and free ocean tide models to the computation of semidiurnal, diurnal and long-period tides, it is recognized that the basin dominating features of theExpand
