Radio propagation is afflicted by daily changes of water vapor within the troposphere and ionization within the upper atmosphere, due to the Sun. Radio propagation is the behavior of radio waves if they are transmitted, or propagated from point on the earth to another or into some part of the ambiance. As a type of electromagnetic radiation, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and spreading.
