WebWe often think of the ionosphere as having a number of distinct layers. This is convenient for many explanations, but it’s not en-tirely accurate as the entire ionosphere contains ionized molecules (and free electrons). Instead, the layers are best thought of as peaks in ionization levels. To quickly identify the layers, peaks or regions, we ...
