A Characteristic Signature of Magnetospheric Wave-Particle Interactions Found in the Turbulent E-region
Read more of: A Characteristic Signature of Magnetospheric Wave-Particle Interactions Found in the Turbulent E-regionPlasma waves in the magnetosphere scatter electrons, causing them to precipitate into Earth’s atmosphere, imparting their temporal characteristics to diffuse auroras. In a case study of conjugate radar and satellite […]
