Investigation of Auroral Ionospheric and Propagation Phenomena Related to the Polar Fox II Experiment

Auroral phenomena can have pronounced effects upon HF radiowave propagation traversing polar regions. To further understand the implications and predict the resulting effects, a continuation of the investigation of auroral phenomena and their impact upon Polar Fox II measurements is presented.

Description
Summary:Auroral phenomena can have pronounced effects upon HF radiowave propagation traversing polar regions. To further understand the implications and predict the resulting effects, a continuation of the investigation of auroral phenomena and their impact upon Polar Fox II measurements is presented. In the report, special emphasis has been placed on a study of the fine structure and motions of spread F as related to spectral spreading; the main ionospheric trough and magnetic activity; analysis of radar auroral absorption and Auroral sporadic E as they relate to propagation coverage predictions. Prepared in cooperation with Analytical Systems Corp., Burlington, Mass. (Rept. no. ASCR-72-62).
