Plasma physics

In atmospheric electricity, the number of ions per unit volume of a given sample of air; more particularly, the number of ions of a given type (positive small ion, negative small ion, positive large ...

sporadic E

Physics; Plasma physics

A phenomenon occurring in the e region of the ionosphere, which significantly affects HF radiowave propagation. Sporadic E can occur during daytime or nighttime and it varies markedly with latitude.

upper atmosphere

Physics; Plasma physics

The general term applied to the atmosphere above the troposphere or upper air.

incoherent scattering

Physics; Plasma physics

The phenomena of generating waves with random variations in phase, amplitude, polarization, and direction of propagation when an incident wave encounters matter.

F-region

Physics; Plasma physics

The upper layer of the ionosphere, approximately 120 to 1500 km in altitude. The F region is subdivided into the F1 and F2 regions. The F2 region is the most dense and peaks at altitudes between ...
