1. e layer

   The Heaviside layer, sometimes called the Kennelly–Heaviside layer, named after Arthur E. Kennelly and Oliver Heaviside, is a layer of ionised gas occurring roughly between 90km and 150 km (56 and 93 mi) above the ground — one of several layers in the Earth's ionosphere. It is also known as the E region. It reflects medium-frequency radio waves. Because of this reflective layer, radio waves radiated into the sky can return to Earth beyond the horizon. This "skywave" or "skip" propagation technique has been used since the 1920s for radio communication at long distances, up to transcontinental distances. Propagation is affected by the time of day. During the daytime the solar wind presses this layer closer to the Earth, thereby limiting how far it can reflect radio waves. Conversely, on the night (lee) side of the Earth, the solar wind drags the ionosphere further away, thereby greatly increasing the range which radio waves can travel by reflection. The extent of the effect is further influenced by the season, and the amount of sunspot activity.

1. e layer

   The E layer, also known as the Kennelly-Heaviside layer, is one of the layers in the Earth's ionosphere, situated at an altitude of about 90-120 kilometers above the Earth's surface. It is primarily ionized by UV radiation from the Sun, making it the region of the atmosphere that reflects medium-wave radio signals, enabling long-distance communication. Its ionization can vary greatly based on the level of solar radiation, often disappearing completely at night.
