Abstract:

Satellite-borne electric field measurements using the double probe technique have now provided a comprehensive survey of convection electric fields at low altitudes in the magnetosphere. The most prominent features of the convection electric fields are reversals located at high magnetic latitudes, with generally anti-sunward convection poleward and sunward convection equatorward of the electric field reversal location. The electric field reversal is usually coincident with the trapping boundary for electrons with energies E 45 keV and is interpreted as the boundary between open and closed magnetic field lines. On the day side of the magnetosphere the electric field reversal is observed to coincide with the equatorward boundary of the polar cusp. Author
