E REGION Meaning and
Definition
-
The term "e region" refers to a specific region of the Earth's ionosphere, a portion of the upper atmosphere containing charged particles called ions. The e region, also known as the Heaviside layer, exists between approximately 90 to 150 kilometers above the Earth's surface. It lies above the D region and beneath the F region of the ionosphere.
In the e region, the concentration of ions is relatively high, resulting in increased ionization and conductivity of the atmosphere. This means that radio waves with frequencies between 3 to 30 megahertz (MHz) can be refracted and reflected by the ionized particles in this region, allowing for long-range communication over large distances (both terrestrial and atmospheric wave propagation).
Due to the presence of daytime ionization and solar heating, the e region experiences significant diurnal variations. During daytime hours, the e region is more highly ionized and is often divided into two sub-layers: E1 and E2. The E1 layer is closer to the Earth's surface and primarily consists of small, singly-ionized metallic ions, while the E2 layer is positioned higher and contains more doubly-ionized ions.
The e region plays a vital role in radio communication, particularly for long-distance high-frequency (HF) radio transmissions. Understanding the behavior and characteristics of the e region is crucial for scientists, radio engineers, and radio operators, enabling them to optimize the range and reliability of communication systems that depend on this part of the ionosphere.

Etymology of E REGION
The phrase "e region" does not have a specific etymology as it is a scientific term that has been abbreviated. However, I can provide the origin of the two components that make up the phrase:
1. "E": In the context of atmospheric science and the study of Earth's ionosphere, "E" refers to the E-layer. The "E" designation comes from the German word "Einschichtig" meaning "single layer" or "stratum". It was initially used by German researchers to describe a layer of the ionosphere characterized by the presence of positively charged ions. The concept of the E-layer was first introduced in the early 20th century.
2. "Region": The word "region" has its roots in Latin. It derives from the Latin word "regio" meaning "district", "boundary", or "territory".
