Ion thermal effects on E-region instabilities: 2D kinetic simulations
E-region electrojet Ionospheric irregularities Plasma instabilities
2017/3/22
Radars frequently receive strong returns from naturally occurring plasma density irregularities centered around
100 km altitude in the atmosphere. These E-region ionospheric irregularities occur when...
