Radio Astronomy: A Revision of Chapter 22, Handbook of Geophysics and Space Environments

This survey is a summary of available information on radiation environments at radio frequencies (about 10 m to 1 cm wavelength); the Moon, the Planets, and space beyond the solar system are described. The topics presented are refraction and absorption of extraterrestrial radio waves by the Earth's atmosphere, radio and radar observations of the Mo^n and Planets, radio emission from the celestial sphere (background radiation), discrete sources of continuum radio emission, and spectral-line radiation from neutral atomic hydrogen and from the hydroxyl radical (OH).
