magnetosphere jonosphere Natural emissions and man-made noises
ULF and LFion plasma diagnostics, E B field fluctuations. VLFlow density plasma diagnostics HFelectron plasma diagnostics, Solar radio burst. Wave in situ diagnostics Local plasma frequency =local electron density tens kHz up to few MHz Local gyro-frequency proportional to theintensity of magnetic field tenskHz up to MHz The ionosphere represents less than 0.1% of the total mass of the Earth's atmosphere. Even so, it is extremely important!
