The first ionospheric layer found was the so called E layer or region at about 110 km altitude. It is used by radio operators as a surface from which signals can be reflected to distant stations. It is interesting to note that this works also the other way round and, for example, the auroral kilometric radiation created by the precipitating particles high above the ionosphere does not reach the ground because of the ionospheric E layer. Above the E layer, a F layer consisting of two parts can be found : F1 is at about 170 km, and F2 at about 250 km altitude. Also F layer reflects radio waves. The lowermost region of the ionosphere below 80 km altitude, D layer, however, principally absorbs radio waves. 2, record 5, English, - ionospheric%20layer

La couche ionosphérique est donc ionisée, et ce de manière discontinue. Elle a donc été divisée en couches distinctes, la première à avoir été détectée étant la région E (couche de Kennelly-Heaviside). Par ordre alphabétique, on a ensuite la couche F située au-dessus de la couche E. La couche F se subdivise généralement en deux couches, la couche F1 située vers 170 km et la couche F2 située au-delà de 250 km. La couche D, située entre 60 et 90 km échappe au sondage vertical (méthode des échos). De plus, les tailles des différentes couches variant alors avec la température, on peut distinguer une nette différence de leurs importances, selon que ce soit le jour, ou la nuit (pas de couche D, et peu de F). 2, record 5, French, - couche%20ionosph%C3%A9rique

The D layer is the closest layer to the Earth’s surface, and also forms only during daylight hours. This layer is a layer which instead of refracting signals to Earth, absorbs them. The D layer absorbs high frequency and medium frequency radio signals. In fact, sometimes, D layer absorption can grow so great that all radio communications by way of the ionosphere are wiped out for a short period. 6, record 6, English, - D%20layer

Lors d'une activité solaire intense, certaines transmissions radio sont tellement perturbées qu'elles entraînent parfois un véritable «black-out» des communications. Dans le cas d'une éruption solaire, c'est la brusque augmentation de la concentration électronique dans la couche D qui provoque une atténuation tellement forte de l'intensité des ondes radio de courte longueur d'onde (10 à 100 m), que la réception de celles-ci devient inaudible. Par contre, les ondes de grandes longueurs d'onde sont réfléchies à un niveau plus bas de la couche D. 4, record 6, French, - couche%20D
