Equatorial E 8 and Daytime Blanketing E 8 Drifts at Ibadan

The daytime measurements of the velocities and other fading characteristics of equatorial E s and blanketing E s irregularities in the frequency range 4–6 MHz are presented for Ibadan. The modes of signal returns by the two groups of E s are discussed. The experimental results suggest that the equatorial E s irregularities observed in the 4‐6 MHz frequency range at Ibadan are of a similar nature to those observed at 50 MHz at Huancayo during a weak electrojet. A tentative inference from the equatorial E s results is that the magnitudes of equatorial E s velocities may be independent of the relative strength of electrojet intensity.
