WebWhat is the ionosphere? The ionosphere is the ionised part of the atmosphere that extends from an altitude of around 50 km to more than 1000 km. There are a significant number of free electrons and positive ions although it is electrically neutral. The level of ionospheric activity is generally described in terms of electron density. The ...

Web1 jan. 2011 · The ionosphere has been extensively studied for more than 60 years with a variety of measurement techniques and modeling approaches (cf. Schunk and Nagy, 2009), and it is now clear that the ionosphere is highly dynamic and exhibits a significant amount of spatial structure.Over the years, numerous modeling schemes have been used to … Web14 apr. 2024 · The ionosonde is essentially a high frequency radar which sends short pulses of radio energy into the ionosphere. If the radio frequency is not too high, the pulses are reflected back to earth. The ionosonde records the time delay between transmission and reception of the pulses. By varying the frequency of the pulses (typically 1-22 MHz), a ...
