Abstract:

This study on ionization in the auroral zone involved data reduction and analysis to determine 1 the electrodynamics of the auroral E layer and 2 the origin and evolution of high-latitude F-region plasma-density structure. Data obtained by the Chatanika incoherent-scatter radar as well as by rockets and satellites were used in the study. The results are especially useful in characterizing the morphology of E-region conductivity enhancements, and the production, transport, and decay of F-region plasma throughout the auroral zone. The relationship between currents both perpendicular and field-aligned and electric fields has also been studied. In addition to these experimental investigations, SRI has contributed new theoretical concepts in the areas of cross-field plasma diffusion and global plasma-density irregularity morphology.
