Exactly what I needed to learn how the sun affects the ionosphere. I understood the structure of the ionosphere and how it reflects radio waves, but I didn't understand enough about how the ionosphere is affected by changes in the sun--the sunspot cycle, coronal mass ejections, etc.

This is fascinating stuff and still a new field, with more experimental data every day. I'm pretty sure that this 2008 book is still accurate in 2018, but it might need a revision by 2028.

I need to learn more detail about the ionosphere and radio, for example, why do the E and F layers reflect radio waves while the D layer absorbs them. But that is outside the scope of this book.

Conceptual physics knowledge is enough to understand the material. I think the Bohr model of the atom and electromagnetics are college physics subjects, but everything else is high school physics. Equations are occasionally included as examples, but they aren't necessary to understand the chapters. College-level topics, e.g. the Bohr model, are explained as needed.… (mer)
