The texture of this globe showcases the variations in Earth's gravity field as measured by NASA's Gravity Recovery and Climate Experiment (GRACE) where very presice microwave measurements between the two pacecraft, GRACE-1 and GRACE-2, were used to map gravity's effect on them with high precision.
In this colouration white/red corresponds to mass excesses and blue corresponds to mass deficiencies.
