“…Since these echoes do not blanket (hide) the higher F-region people speak glibly about the E s layer having 'holes' (Renau, 1961). Recent studies of E s have shown that the E s can be structured at a variety of wavelengths which cause partial backscattering of HF and higher-frequency radio waves (Whitehead, 1989;Mathews, 1998), so 'holes' are no longer in vogue.…”

Two features of the daytime sporadic E echoes observed on ionograms obtained near the magnetic equator have been termed ‘equatorial sporadic E’ and ‘equatorial slant sporadic E.’ These are traces that project from the E‐layer trace and have equivalent ranges independent of frequency and proportional to frequency, respectively. Radar studies in Peru indicate that a thin stratum of magnetic‐field‐aligned irregularities embedded in the E layer is responsible for the entire sporadic E configuration. The increased equivalent ranges of the slant trace are attributed to oblique propagation in the east‐west plane orthogonal to the irregularities. By accounting for the refraction and retardation imposed by the E layer, the entire configuration can be simulated in detail. It is established from this analysis that the equatorial electrojet flows within the equatorial E layer, and that its first‐order current variations are coherent over distances of 500 km or more along the magnetic equator.

Theory of overhead nonblanketing sporadicE

Abstract: We suggest a model for overhead nonblanketing sporadic E based upon scattering from a belt (1 or 2 km in thickness) of irregularities within a stratified E layer. Predicted h′f curves are compared with observed data and found to be in good agreement.
