		A region of the ionosphere, extending from about 90 to 150 kilometers (55 to 95 miles) above the earth and influencing long-distance communications by strongly reflecting radio waves in the range from one to three megahertz.
		Also called E region, Heaviside layer, Kennelly-Heaviside layer.

	Kennelly-Heaviside layer - Wikipedia, the free encyclopedia
		The Kennelly-Heaviside layer, also known as the E region or just as the Heaviside layer, named after Oliver Heaviside, is a layer of ionised gas occurring at 90-150km in above the ground — one of several layers in the Earth's ionosphere.
		During the daytime the solar wind presses this layer closer to the Earth, thereby limiting how far it can reflect radio waves.
		The "Heaviside layer" is used as a symbol for heaven (in the afterlife sense) in Andrew Lloyd Webber's musical Cats.

		This image represents a depiction of the surface topography of the object to be examined or the topography of a boundary layer with a determined reflection behavior.
		Layer images of this kind can be obtained, for example, with a monochromatic confocal scanning microscope or also with a laser scanning microscope.
		In this case, the respective maximum intensity value of the approximation curve in the object depth range represented by the layer images A, B, C, D, E is correlated with the characteristic parameter.

		A switching element (e.g., 30) is furnished by an inversion layer (e.g., 55) in a zero resistance state under the influence of a quantizing magnetic field, the inversion layer having a ring geometry.
		In the device element of this invention, by contrast, during operation the inversion layer (as opposed to the percolating current) always extends all the way around the annular ring; that is, regardless of whether the device is in the ON or OFF state, the inversion layer is never interrupted.
		The purpose of the amorphous silicon layer 330 in the device 300 is to ensure the continued existence of an inversion layer in the underlying silicon.

		At daytime the D layer, which is at an approximate height of 30-60 miles in the mesosphere totally absorbs medium wave rf signals most of the time.
		However the fly in the ointment is the fact that the D layer does not totally disappear at night.
		In a sense the E/F layer duct is shut down and the mediumwave frequency RF signal only propagates between the E layer and land/ocean surface, with a higher angle and more loss.

	HF Radiation - Choosing the right frequency (Site not responding. Last check: 2007-11-05)
		For the last ray (lowest transmission angle) the E layer MUF is greater than the transmission frequency and the ray is unable to reach the F layer.
		Above the D layer, the is some absorption, but it is much less than in the D layer because there are fewer neutral atoms.
		Also during the night, the E layer MUF is lower and therefore it is more likely that the ray will pass through the E layer and be refracted in the F layer at a higher elevation (higher blue ray).

		With E layer propagation it would appear that the rule is valid - most obvious when the signals to North America decline, if not disappear on 28MHz, at the times when the band opens on 50MHz, much the same as F layer propagation.
		Under the old model of E layer propagation this path would either a) not be possible or b) only be explained by the very accurate lining up of at least 2 clouds or reflecting zones within the layer at just the right point.
		On the subject of night time Es, I suggest that although the sun may have set at a location, as far as the E layer is concerned it is still daylight, or in a few extreme cases the E layer is so excited, it does not have time to die.

	Lightning-induced intensification of the ionospheric sporadic E layer : Abstract : Nature
		Lightning-induced intensification of the ionospheric sporadic E layer
		, that the ionospheric 'sporadic E' layer—transient, localized patches of relatively high electron density in the mid-ionosphere E layer, which significantly affect radio-wave propagation—can be modulated by thunderstorms, but a more formal statistical analysis is still needed.
		Because no ionospheric response to low-pressure systems without lightning is detected, we conclude that this localized intensification of the sporadic E layer can be attributed to lightning.
