Ground wave

A wave that is propagated over the earth and is ordinarily affected by the presence of the ground and the troposphere. The ground wave includes all components of a radio wave over the earth except ionospheric and tropospheric waves.

Note: The ground wave is refracted because of variations in the dielectric constant of the troposphere including the condition known as the surface duct.
