High-frequency radio wave absorption in the D-region

Abstract
Polar Cap Absorption (PCA) events are triggered by highly-energized solar particles gaining access to upper regions of Earth's atmosphere at high latitudes.  These energized particles can be the result of solar flares and coronal mass ejections.  PCA events are associated with significant attenuation of high-frequency radio signals propagating through the ionosphere via paths over polar regions.  However, the degree to which these events depend on solar wind parameters is not fully understood, nor is their impact on high-frequency (HF) radio communications.  As a first step in understanding the mechanisms of PCA events, a thorough study of HF radio wave absorption was initiated.  This presentation is a review of that study. This presentation was given to the USU physics faculty on 30 March 2017. It was well received.
