The aspect sensitivity of spread-F irregularities
Journal of Atmospheric and Terrestrial Physics, 1971Abstract A high latitude oblique incidence echo, previously shown to be produced by irregularities strongly aligned along the magnetic field, is found to occur whenever vertical incidence spread- F is recorded from the same volume of the F -layer.

Quantifying spread F by digital ionosondes
Advances in Space Research, 2003The width of frequency-spreading (Δff) on ionograms was shown (Wright, et al., 1977, by comparison with OGO-6 Satellite observations) to be proportional to ΔNN near and above the F-region peak. Thus, even classical analog ionograms using logarithmic frequency scales were direct reading for this important parameter, although little use has been made of ...

Plasma density discontinuity and spread F
Journal of Atmospheric and Terrestrial Physics, 1984It is shown that the generation of the equatorial spread F irregularity in the post-sunset period need not he always at the base of the F region. The irregularities are generated at the E region, provided there existed a retardation type E2 layer or a uniform blanketing sporadic E layer before the sunset.

An analysis has been made of spread-F data obtained from I.G.Y. f{hook}-plots for several ionosonde stations grouped about longitude 75°W, to establish whether there is any connexion between the incidence of spread-F and f{hook}0F2, F-layer electron content and semi-thickness.

An analysis has been made of spread-F data, obtained from I.G.Y. f{hook}-plots for several ionosonde stations grouped about longitude 75°W to establish whether there is any connexion between the incidence of the frequency-spreading component of spread-F and the vertical movement of the F2-layer.
