Earth’s Gravity Mapped in Unprecedented Detail
“ESA’s GOCE mission has delivered the most accurate model of the ‘geoid’ ever produced, which will be used to further our understanding of how Earth works.
The geoid is the surface of an ideal global ocean in the absence of tides and currents, shaped only by gravity. It is a crucial reference for measuring ocean circulation, sea-level change and ice dynamics – all affected by climate change.
A better knowledge of Earth’s gravity field and its associated geoid will significantly advance our understanding of how the Earth system works. An accurate model of the geoid will advance our understanding global ocean circulation patterns and sea-level rise.”
