Abstract

Tidal variations, which result from the gravitational forces imposed by celestial bodies such as the sun and moon on the earth's masses of water, exhibit recurring alterations in the levels of the oceans. The conventional approach for monitoring tides entails the use of tidal gauges, however, satellite altimetry offers an alternate means of measurement. Tide gauges provide accurate measurements, albeit their effectiveness is contingent upon their specific geographical placement. On the other hand, altimetry satellites provide worldwide coverage, but with less temporal resolution. A least squares harmonic analysis is employed to examine tidal components using altimetry satellites. Nevertheless, this approach has a diminished temporal resolution in comparison to tide gauges. The present work aims to extract sea surface height data of the Jason-3 altimetry satellites to estimate sea surface heights, and subsequently compares these estimates with human tidal gauge readings. The study centers on the measuring of amplitude and phase of individual tidal components. The findings of this study reveal that the K1 tidal component demonstrates the biggest average difference, as measured by the root mean square error (RMSE), with a value of 0.360 m.
