On the plasma instability mechanisms responsible for Esq

Abstract

Evidence is presented showing that the gradient drift (type 2) irregularities are the most probable scatterers responsible for equatorial sporadic E (Esq) echoes observed on conventional equatorial ionograms and that the two‐stream (type 1) irregularities are not detectable at ionosonde wavelengths (1–10 MHz).
