WebJul 26, 2024 · Rayleigh Doppler wind lidar is an efficient and important way to detect the wind field in the stratosphere and mesosphere with high time and spatial resolution. The first wind measurement in the stratosphere up to 50 km was realized in 1989 [Chanin et al., 1989; Garnier and Chanin, 1992; Souprayen et al., 1999a, 1999b]. WebThe possibility to measure winds in the middle atmosphere with a Doppler LIDAR was demonstrated in 1989. It has been used since then to study the wave-mean flow …
WebA new method of simultaneous remote sensing of atmospheric wind and temperature by a ultraviolet Rayleigh lidar is described. This technique uses two narrowband filters located … WebA Rayleigh Lidar used for wind detection works by transmitting laser pulses to the atmosphere and receiving backscattering signals from molecules. Because of the weak backscattering signals, a lidar usually uses a high sensitivity photomultiplier as detector and photon counting technology for signal collection.
