GOCE Global Gravity Field Models and Grids

GOCE Global Gravity Field Models and Grids is an ESA Level 2 collection of static gravity-field products derived from the Gravity field and steady-state Ocean Circulation Explorer mission.^[1][2] The collection includes spectral representations of the gravity potential, gridded geoid heights, gravity anomalies, error information, and calibrated gravity gradients in multiple reference frames.^[1] Release 6 files include GOCE gravity-field model products and covariance products in packaged TGZ form, with coefficient files also exposed in ICGEM IDF format.^[2]

The product is a static geodetic and geophysical layer, not a time-variable mass-change product. It supports ocean dynamic topography and sea-level work by providing a geoid surface against which sea-surface height can be interpreted.^[3] It also supports regional solid-Earth and mineral-prospectivity studies as a gravity anomaly constraint that can be combined with magnetic, seismic, and geological layers.^[2] Spatial interpretation remains regional because the GOCE mission design targets geoid and gravity anomaly performance at about 100 km scale; local mineral targeting still requires higher-resolution airborne, ground, or borehole data.^[4]
