About Trapped Particle Models at SPDF
The flux of trapped electrons and protons in the Earth's radiation belt has
been measured by a large number of satellites over the last three decades.
Knowledge of the particle environment is essential for estimates of the
radiation exposure of humans and materials in space. J. Vette and his
colleagues at NSSDC have developed and improved empirical models for the
trapped particle fluxes since the mid-sixties. The particle fluxes can best be
described in terms of the coordinates B/Bo and L; Bo is the magnetic field
strength at the magnetic equator (minimum value). Application of these models
requires, therefore, the use of a geomagnetic field model.
