Short summary
The ionosphere, formed by atmospheric ionization, contains free electrons and ions. Incoherent Scatter Radar probes it using high-frequency electromagnetic pulses, revealing ionospheric properties. Plasma lines, weak at thermal equilibrium, are enhanced and become detectable due to strong solar or auroral activity. This study develops methodologies to detect plasma lines, showing their strength decreases as the scattering radar beam is more oblique to the Earth's magnetic field.
