Webtides and solid Earth tides. Ocean tide corrections are computed from a model that defines the tidal surface relative to a mean surface associated with the deformed solid Earth. The solid Earth tide correction reflects the vertical displacement of the crust of the Earth with respect to the ellipsoid due to the attraction of the Sun and Moon. This WebDec 20, 2024 · Earth and ocean tides. The solid Earth responds to the pull of the Sun and the Moon just like the oceans, but movements are much smaller. The Sun and the Moon also pull on the gravimeter and its parts. These effects are large enough to affect gravity readings .
