The tropopause can be detected and its altitude determined routinely with the use of meter-wavelength, very-high-frequency radar. At meter wavelengths and at vertical incidence, the tropopause is revealed by partial specular reflection from stable atmospheric layers. The echoes received at vertical incidence as a result of partial specular reflection are greatly enhanced over echoes received at oblique incidence arising from turbulent scatter. Very-high-frequency radars utilizing partial specular reflection promise a major advance in the remote sensing of the atmosphere.
