Abstract The stability of ionospheric layers is investigated. A bounded layer, represented mathematically by a Gaussian layer plus background, is adopted as a model ionization density. Such a model is a good representation of the ionospheric situation and allows an unambiguous interpretation of positive growths of the instability. The electron and ion flow equations and the continuity equations are used to represent low-frequency, macroscopic variations in plasma density and electric potential. The differential equation developed is asymptotically expanded in terms of a parameter. The first-order solutions obtained are then used to derive a dispersion equation for the complex eigenfrequency. Calculations show that the imaginary part leads to positive growths, indicating that instabilities could arise in equatorial and mid-temperate sporadic E-layers.
