The data were developed by professor david t.
This satellite altimeter data base contains precise geoid and gravity anomaly profiles which were constructed from the average of 66 repeat cycles of geosat.
Data parameters include latitude longitude observed gravity and elevation bouguer gravity anomaly land and free air anomaly ocean.
Note that odd values of topography e g 2001m are constrained by actual soundings while even values e g 2000m are predicted from gravity.

The research is discussed in a related paper in science.
We also incorporated data from the following missions.
The satellite altimetry data from cryosat 2 is being provided by esa while data from the jason 1 mission was provided by the national aeronautics and space administration nasa and the centre national d études spatiales cnes.
