ionogram at Kokubunji, Tokyo, Japan
Abstract:
Recorded tracings of high-frequency (HF) radio pulses reflected in the ionosphere. This ionograms are produced by an ionosonde at Kokubunji, Tokyo, Japan. The ionosonde sweeps HF radio pulses from 1MHz to 30MHz, basically every 15 minutes. The transmitted radio pulses travel more slowly within the ionosphere, depending on the ionospheric plasma density. The apparent height, that is, virtual height of the reflection point is recorded for each frequency of the transmitted HF radio wave. When the frequencies become higher than the maximum plasma frequency of the ionospheric layer, the radio wave pass through the layer and be lost in space. The profile of the ionospheric plasma density can be obtained from this data.
