WebThe regular variations that affect the extent of ionization in the ionosphere can be divided into four main classes: daily, seasonal, 11-year, and 27-day variations. DAILY. - Daily variations in the ionosphere are a result of the 24-hour rotation of the Earth about its axis. Web10 apr. 2024 · Given that the ionosphere is strongly determined by the thermosphere and its state depends on thermospheric parameters, we propose a new method to extract exospheric temperature (T ex) from electron density (Ne) profiles based on the relationship between the variations in T ex and Ne profiles established through simulation. Ne …
