WebbThe lower region of the thermosphere (up to about 550 kilometers) is also known as the ionosphere. Because of the high temperatures in this region, gas particles become ionized. The ionosphere is important because it reflects radio waves from the earth’s surface, allowing long-distance radio communication. Webb13 maj 2024 · Density measurements as low as 130 km inferred from the decay of low-altitude satellites have been useful for the understanding of gross features of the lower thermosphere, but temporal scales, variability, spatial scales and structures as well as composition of the transition region in particular near 100–200 km remains obscure.

WebbVoir l’historique. L' ionosphère d'une planète est une couche de son atmosphère caractérisée par une ionisation partielle des gaz. Dans le cas de la Terre, elle se situe entre environ 60 et 1 000 km d'altitude et recouvre donc une partie de la mésosphère, toute la thermosphère et une partie de l' exosphère .
