Web28 apr. 2024 · Ionosphere Layers: Day-Night and Latitude Dependencies The ionosphere is the ionized part of the Earth’s atmosphere. It is formed by a group of electrons and electrically-charged particles, starting at an approximate altitude of 60 km. WebThe ionosphere has more time to recombine during the long winter nights, resulting in weaker and longer low-level electron density periods. The longer daytime hours in the summer cause the F2 layer to increase due to a heating process. As a result, the ionisation density is lower than in the winter.
