Summary

Important problems in magnetospheric and ionospheric physics involve the global electric field distribution and its relation to auroral arcs. If continuous observations of electric fields and auroras were available throughout the auroral zone and polar cap, it would be possible to determine the large-scale polar convection pattern for the first time, to identify the location of auroral arcs with respect to the convection pattern, and to determine the evolution of electric fields relative to that of auroras during substorms. This information, which cannot be obtained from presently available data, is required to fully understand the transfer of solar wind energy to the magnetosphere via the convection electric field, auroras, and substorms.
