Polar Fox II Study Phase
Abstract
Auroral phenomena related to HF radiowave propagation are investigated to establish regions where and times when spectral spreading, backscatter echoes and radiowave absorption may be expected on signals propagating in polar latitudes. The spatial and temporal patterns of energetic particle precipitation are summarized in relation to ionospheric effects observed in the D, E and F regions to provide a background for the analysis of similar patterns in auroral ionospheric phenomena.
