HALO Wind Lidar

PI: Johannes BühlParametres: Wind Components, Wind Speed, Wind Direction, Attenuated Backscatter(1.5μm), Doppler Velocity, Dissipation Rate

The Streamline-XR Doppler lidar of HALO Photonics company emits infrared light at a wavelength of 1.5μm. It has a maximum vertical resolution of 18m and it is sensitive to backscatter coefficient and velocity of the observed aerosol particles. Usually the system is operated in vertical-stare mode, measuring the vertical component of the wind. Every 10min, the lidar performs a conical scan for retrieving the 3D wind vector. In this way, the distribution of wind speed and direction can be derived within the turbulent mixing layer and at cloud bases.
