Comments
A lidar (LIght Detection And Ranging) system uses lasers to probe the atmosphere. It makes use of Rayleigh scattering of light from atmospheric molecules to detect relative particle densities, absolute temperatures, and periodic phenomena such as gravity waves. The Rayleigh-‐scatter lidar system at Utah State University employs a pulsed Nd:YAG laser, frequency doubled to 532 nm, to measure such atmospheric properties, formerly only in the mesosphere. It is currently being upgraded to make it the most sensitive of its kind and to provide continuous coverage from the stratosphere to the lower thermosphere, 15-‐110 km.
