Global geoid models map the Earth's gravitational field. The surface of the geoid passes through the middle oceans of the world. The models are calculated using satellite data and are indispensable for global altimetry, the study of sea level rise, and the study of polar melt. The geoid differs from the ellipsoid by about -100 m to +100 m.

Two variants are freely available.
