Measurement of Sporadic E-Layer lonization

Nature, 1949
THE usual measure of sporadic E-layer ionization is the so-called 'critical frequency', that is, the highest reflected frequency for this layer. While this definition is suitable for all other ionospheric layers, it is not sufficient for the sporadic E-layer (Es), because it consists of ionized clouds and has no homogeneous ionization.

Sporadic E-layers as current generators

Radiophysics and Quantum Electronics, 1996
Quasi two- and three-dimensional models of dense night-time sporadic E-layers of the earth's ionosphere as current generators are developed. The layers are assumed to be situated in an ambient plasma of about fifty times lower density and their neutral particles possess a rather high bulk velocity relative to the ions.

Sporadic-E layers and unstable wind shears

Journal of Atmospheric and Terrestrial Physics, 1980
Electron density profiles of sporadic-E layers have been observed with good height resolution using rocket-borne probes. These generally show a simple shape consistent with the effect of a linear wind shear acting on metallic ions. Occasionally more complex shapes have been recorded, including double peaks and, on one occasion, a nearly rectangular ...

Fine structure in midlatitude sporadic E layers

Journal of Atmospheric and Solar-Terrestrial Physics, 2013
Abstract Fine structure in midlatitude sporadic E layer patches or “clouds” is apparent in incoherent scatter observations from the Arecibo Radio Telescope. The fine structure is wavelike with predominant horizontal wavelengths as large as about 2–3 km. We attribute the structure to a drift wave instability operating in the collisional regime.
