Sandwell Satellite Gravity Data

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 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. In 2008 we generated a version of satellite gravity we termed the trident solution by stacking three independently derived solutions of free air gravity from the geosat and ers 1 satellites.
