Visualization of Gravity Field Models and their Differences

This is an interactive web site (based on Javascript) to visualize the Geoid and other gravity functionals of the Earth. Please have some seconds patience for generating the image on the server.
The Geoid undulations are multiplied with a so-called radial 'boost factor' (initial value: b = 10,000) to make them visible.
You can select another Functional, gravity Model and Subtrahend model (to display model differences).
The option Grid defines the resolution of the view: smaller values show more details, but require more computing time (on the server).
