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

NetCDF files made by UNAVCO using the GUT:

Data source:

The NGS GEOID09 is a hybrid geoid to converts heights from NAD 83 to regional Vertical datums (e.g., NAVD 88 , GUVD04, ASVD02, NMVD03 and the future vertical datums PRVD02 and VIVD09). These geoid heights are only reliable within CONUS due to the limited extents of the data used to compute it. See also Geophysics of the Geoid.

24 to 58 North; 230 to 300 East longitude.
