HF Propagation Degradation during Ionospheric Storms.

Abstract

A comparison of storm effects over eight Pacific oblique sounder paths provides guidelines for spectrum utilization for the Naval communication station communicator and traffic manager. Hf circuit degradation due to ionospheric storms is shown to be latitude-dependent. During severe disturbance periods the existing hf usable spectrum is highly unstable. Hf frequencies in the middle of the normal daytime usable spectrum have the highest probability of survival, but point-to-point oblique sounding is the only reliable method for maintaining maximum transmission circuit availability during storm periods.
