WebIf the Gleason projection is accurate, the earth is around 25,000 miles in diameter from “ice wall” to “ice wall”. If the earth was flat and the stars were inside the “dome”, then we can see stars on the horizon which are over 15,000 miles away. In reality, we can NOT see a city’s lights and skyscrapers from 100 miles away, even ...

WebAbstract. Methods taking into account the effect of tidal forces on gravity measurements are considered. Corrections for the effect of tidal forces can exceed 250 μGal. Only the structure of the Earth and positions of tide-generating celestial bodies are necessary for taking into account earth tides, while cotidal charts are additionally ... 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

Webbe observed if Earth were a perfect (no geologic or topographic complexities), rotating ellipsoid is referred to as the normal gravity. Gravity INCREASES with increasing latitude.
