            "description": "This is a simulation of the Earth's radiation belts constructed from SAMPEX data around the time of the 2003 Halloween solar storms. In this visualization, we present the belts in cross-section to provide a better view of their interior structure.The Earth's magnetosphere is a very large magnetic structure around the Earth, and gets stretched into a large, teardrop-shaped configuration through its interaction with the solar wind. A number of the magnetic field lines, while they may originate on the Earth, do not connect back to the Earth, but connect into the magnetic field carried by the solar wind. However, near the Earth, the magnetic dipole component of the field is stronger than the solar wind field, and this allows all the magnetic field lines to connect back to the Earth, forming (approximately) the classic magnetic dipole configuration (Wikipedia). In this region, lower energy electrons and ions, many from the Earth's ionosphere, can become trapped by the magnetic field to form the radiation belts.The radiation belt model is constructed from particle flux information from the SAMPEX mission, with the flux mapped to constant L-shells of the Earth's dipole magnetic field (Wikipedia). The model is anchored to the Earth's geomagnetic field axis, which is not perfectly aligned with the Earth's rotation axis. This creates a small wobble of the radiation belts with time, which can be seen in this visualization.The data driving the radiation belt structure is from the 2003 Halloween solar storms, a series of strong solar eruptions that began in late October 2003 and continued into the first week of November. During this time, the particle content of the belts change rapidly due to the variation in the energetic particle flux from the Sun buffeting the Earth's magnetosphere.This dataset was also used to generate radiation belts for the RBSP prelaunch visualizations. || ",

            "description": "Under the wave of energetic particles from the Halloween 2003 solar storm events, the Earth's radiation belts underwent significant changes in structure.  This visualization is constructed using daily-averaged particle flux data from the SAMPEX satellite installed in a simple dipole model for the Earth's magnetic field.  The toroidal structure of the belts corresponds to regions with electron fluxes in excess of 100 electrons/s/cm^2/steradian with energies of 2-6 MeV.  The color-scale on the cross section is violet for low flux and white for high flux.  The translucent gray arcs represent the fields lines of the Earth's dipole field.  The 3-dimensional structure was built from the SAMPEX measurement by propagating the particle flux values along field lines of a simple magnetic dipole.NOTE:  This visualization shows the Earth's magnetic dipole field lines rotating rigidly with the Earth.  Technically, this is inaccurate.  Ions and electrons in the lower atmosphere can create currents which can make these lines 'drag' with Earth's rotation, but this will occur mostly near the Earth and not higher up.
