Tidal Corrections

Tidal Corrections

Tides on the Earth are driven by the Moon and the Sun (the effect of other planets are small in comparison). As the relative positions of the Earth, Moon and Sun are known very well, it is possible to identify the tide-generating potential of any point on the Earth very well, using a combination of harmonic functions. Improved tidal corrections subsequently lead to a reduction of aliased tidal noise. Removal of said noise is necessary for investigating non-tidal signals of interest. 

Shum et al. (1997) and Stammer et al. (2014) provide detailed overviews of existing methods as well as the associated uncertainties. The GOT4.10c ocean tide model is used with S6-MF.

Full analysis of tidal corrections and their associated uncertainties has not yet been done within this project.
