This image may not be used to state or imply ESA endorsement of any company or product Gravity map of Earth. Computer model showing the variation of the Earth's gravity field centred on Africa and Europe. Colours represent gravity anomaly. These are the differences between the theoretical value for the gravity at the surface, if the Earth was a perfectly smooth ellipsoid, and the actual measured value. They range from purple (low gravity), through blue, green, yellow, orange, red and magenta (high gravity). This model was created from data acquired by NASA's Gravity Recovery and Climate Experiment (GRACE), Laser Geodynamics Satellites (LAGEOS) and surface gravity data. An accurate gravity map enables scientists to better understand the Earth's internal structure and may help predict climate change and natural hazards.
