On land the field have been augmented with the best available terrestial gravity field com complete global coverage.Gravity changes are mainly caused by the changes in the attraction of mass under the surface
 

DTU10 ocean wide gravity field mapped with a resolution of 1 minute by 1 minute corresponding to 2 minute by 2 minute resolution at Equator.
