> How to control the vertical axis scale factor ?

Use the View->Viewpoint->Vertical Scale menu (or click the
icon that looks like a comb on the Viewpoint Toolbar) to
bring up the vertical scale dialog.  The default for 
the globe is -16km to 16km.  0 is the surface of the globe.
For datasets with high altitudes (i.e. low pressures), you
could increase it to be -25 to 25 km.  You might have to 
play around to get the desired effect.  The key is to 
make the range symetrical for the globe display.

> I am using a Globe View window to display an isosurface.
> The isosurfaces are correctly represented by they use a vertical
> axis with high values, thus I got isosurface very high in altitude
> in comparison with the surface of the Earth.
