E LAYER Meaning and
Definition
-
The E layer, also known as the Kennelly-Heaviside layer, is a region in the Earth's ionosphere characterized by a concentration of ionized particles located between 90 and 150 kilometers (56 to 93 miles) above the Earth's surface. It is named after the physicists Arthur Edwin Kennelly and Oliver Heaviside who first theorized its existence in the early 20th century.
The E layer is formed by the absorption of solar ultraviolet radiation that ionizes neutral particles in the atmosphere, resulting in the creation of free electrons and positive ions. These charged particles enable the layer to reflect radio waves with frequencies ranging from approximately 2 to 30 megahertz. This phenomenon, known as "skip propagation" or "skywave propagation," allows radio signals to travel long distances by bouncing off the E layer and back to Earth.
The characteristics of the E layer vary according to factors such as altitude, geographical location, time of day, and solar activity. It is known to exhibit diurnal variations, being more pronounced during daylight hours due to increased ionization caused by the sun's radiation. Additionally, the E layer's density can change as a result of solar flares, geomagnetic storms, and other space weather phenomena.
The E layer plays a crucial role in long-distance radio communication, particularly in the medium frequency (MF) and high frequency (HF) bands. It enables signals to be transmitted over vast distances, allowing for global communication and the propagation of radio waves beyond the line of sight.

Etymology of E LAYER
The term "E layer" has its etymology rooted in the field of radio communication. The "E layer" is a region within the Earth's ionosphere that reflects radio waves. The "E" in "E layer" stands for "Esch" or "Eschelon", named after Friedrich Clemens Eschelbronner, a German physicist who extensively studied radio wave propagation and atmospheric phenomena.
Eschelbronner's work contributed significantly to our understanding of the ionosphere and the layers within it. The "E layer" specifically refers to a specific portion of the ionosphere that reflects medium-frequency radio waves.
Therefore, the etymology of the term "E layer" is derived from the name of Friedrich Clemens Eschelbronner, the physicist who played a key role in the research and understanding of the ionosphere.
