WebIn the lower regions of the ionosphere three-body processes leading to the formation of H 3+and H 5+ions, which have very fast dissociative recombination rates, produce a dramatic reduction in the electron density. WebL' atmosphère est ionisée sur toute la surface du globe à partir d'une altitude d'environ 60 km, au-dessous de laquelle l'ionisation est négligeable ; cette région de l'atmosphère est appelée ionosphère. Vers les altitudes supérieures, l'ionisation s'étend jusqu'à la magnétopause, limite de la zone d'influence du champ magnétique terrestre.

WebThe ionosphere is formed by partially ionized air (plasma) that surrounds the Earth and constitutes an interface between the neutral upper atmosphere and space plasma. The ionosphere influences the propagation and attenuation of electromagnetic waves. Web11 apr. 2024 · Plasma content and distribution are key parameters in the dynamics of the inner magnetosphere. The plasmasphere contributes, for the most part, to the plasma mass density, and its properties are very dependent on the history of the magnetosphere and geomagnetic activity. In this work, we investigated plasmasphere dynamics and …
