| WikiPedia definition of "d-layer" |
|
Solar radiation, acting on the different compositions of the atmosphere with height, generates layers of ionization: D layer. The D layer is the innermost layer, 50 km to 90 km above ...

The D region is the portion of the ionosphere that exists approximately 50 to 95 km above the surface of the Earth. Note: Attenuation of radio waves, caused by ionospheric free ...

In this regard, ISAB is the primary limiting factor in radio propagation. Causes (See ionosphere for more information on the D Layer) Roughly 70% of any possible signal attenuation ...
(More)
As the sun sets, the D layer weakens, allowing Medium Wave radio waves from such stations to bounce off the E layer of the ionosphere, producing reliable, long distance reception ...

As heat is transferred across this boundary by conduction, material in the D" layer becomes hotter and thus more buoyant. When it becomes sufficiently buoyant, material begins to ...

In his 1942 publication of his model, the entire lower mantle was the D layer. In 1950, Bullen found his "D" layer to actually be two different layers.

... vectorization: for example, if a subroutine normally operates on a 2-D matrix array, passing it a 3-D data cube will generally cause the same operation to happen to each 2-D layer of ...

This is primarily because the D layer, which absorbs High frequency signals, disappears rapidly on the dark side of the terminator line. This process is known as skywave ...

... and their depths) are the following: the upper mantle (33–410 km) (20 to 254 miles), the transition zone (410–670 km), the lower mantle (670–2798 km), and the D" layer (2798 ...
