UNAVCO IDV: GOCE Data and Displays UNAVCO IDV: GOCE Data and Displays ESA's Gravity field and steady-state Ocean Circulation Explorer GOCE satellite maps Earth's gravity field in high accuracy.
See Earth's gravity revealed in unprecedented detail.

GOCE data is easily obtained, using ESA's GOCE Users Toolbox (GUT), which makes netCDF format files right for use the IDV.

GOCE and the GUT can provide:

Geoid heights, gravity anomalies, or deflections of the vertical at a given, user-specified, degree and order of the spherical harmonic expansion (i.e. at a given spatial resolution) at the surface of the terrain.

Boguer anomaly at a given, user-specified, degree and order of the spherical harmonic expansion (i.e. at a given spatial resolution) at the surface of the terrain

the height anomaly at a given, user-specified, degree and order of the spherical harmonic expansion

oceanographic height fields

The GUT also provides ACE2 Global DEM with bathymetry.

Data Transects

You can plot transects of data across the map with the IDV. Here are transects from a geoid height difference computation.
