WebThe ionosphere ( / aɪˈɒnəˌsfɪər /) [1] [2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation. 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 profiles …
