彩色土豆，啥东东？
受到籍利平老师《[转载]地球旋转的模拟图象(GOCE数据获得)》http://bbs.sciencenet.cn/home.php?mod=space&uid=255&do=blog&id=429060 启发，真傻找到一个大彩色土豆。
到底这是什么？

哪位专家给讲解讲解吧！谢谢！
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.
A precise model of Earth's geoid is crucial for deriving accurate measurements of ocean circulation, sea-level change and terrestrial ice dynamics. The geoid is also used as a reference surface from which to map the topographical features on the planet. In addition, a better understanding of variations in the gravity field will lead to a deeper understanding of Earth's interior, such as the physics and dynamics associated with volcanic activity and earthquakes.

The mean dynamic topography of the world oceans (in metres) derived from an altimetric sea-surface model combine with a model of the geoid based on just two months of GOCE data.
