E layer

Noun

Meaning

a region of the ionosphere (from 50 to 90 miles up) that reflects radio waves of medium length

Alternative names

e-layer

Synonyms

Examples

After sunset an increase in the height of the E layer maximum increases the range to which radio waves can travel by reflection from the layer. Source: Internet

Around the same time, Robert Watson-Watt, working at the Radio Research Station in Slough, UK, suggested that the ionospheric sporadic E layer (E s ) appeared to be enhanced as a result of lightning but that more work was needed. Source: Internet

During this time very low frequency (3–30 kHz) signals will be reflected by the D layer instead of the E layer, where the increased atmospheric density will usually increase the absorption of the wave and thus dampen it. Source: Internet

At night the E layer weakens because the primary source of ionization is no longer present. Source: Internet

E layer The E layer is the middle layer, convert to convert above the surface of the Earth. Source: Internet

The vertical structure of the E layer is primarily determined by the competing effects of ionization and recombination. Source: Internet
