"This relatively compact book provides a comprehensive review of the basic principles, methodology, and tools for studying the solar variability. The main focus is on measurements and interpretation of the solar properties rather than on theory. It provides both an excellent introduction to the field and an exciting review of the recent advances in solar observations from the ground and space. [...] The Sun's Surface and Subsurface is very well written and nicely illustrated. It should be of interest to a broad cross-section of scientists working in solar and solar-terrestrial physics, space weather, and Earth's climate, and it should be particularly useful to advanced students and young researchers."
