Particle Tracking of the Solar Wind Entry 

and Ionospheric Outflow


About the Models:

A great deal can be learnt about the energetization of particles around the Earth, particularly in the production of very fast (1000 km/s) particles, by using individually particle tracking algorithms, with the electric and magnetic fields provided by the gloabl modeling seen on the other pages. A few examples are shown below, where the particles velocities are color coded - grey/ blue relatively slow at 50-100 km/s, green at ~ 300 km/s and  red at > 1000 km/s.

Movies of The Particles Enviroment around the Earth:

solar wind deflection
A movie (2.3 Mbyte)showing the deflection and energization of solar wind particles at Earth.
Oxygen outflow for the Earth's ionosphere A movie (1.0 Mbyte) showing the loss of ionospheric particles from the northern hemisphere, and the formation of energetic particles rings around the Earth.
Projection of particle motion on the Earth
An important way to monitor space conditions is to sample the particle populations as they move along the terrestrial magnetic field and reach low atitudes. Here is a movie (8 Mbytes) of the mapping of these particles onto the northern hemisphere.
