Multiple data sets are shown in an earth-centered, 3d coordinate system registered with a pseudo-colored topographic globe. The remotely-sensed UV intensity of an aurorae australis is shown as a pseudo-color partial spherical shell. The earth's magnetic field from an emprical model are shown as streamlines pseudo-colored by field strength. Surface magnetic field from ground magnetometers are shown as vector arrows, pseudo-colored by field strength. The position of a spacecraft making in situ observations is shown as a sphere, pseudo-colored by electron temperature, which is sized by electron density, a thin vector arrow indicating the magnetic field direction, pseudo-colored by field strength, and a thick vector arrow showing electron velocity, pseudo-colored by speed.
