The pulsed “Streamline” Doppler Lidar systems from the manufacturer Halo Photonics by Lumibird are operated at an eye-safe wavelength (1.5 µm, laser protection class 1M) and provide profiles of the backscatter intensity of aerosols and clouds, the Doppler wind components and derived profiles of the horizontal wind speed and wind direction. The systems are characterized by their compact design and low weight. They are very easy to set up and offer a comfortable user interface. The scanner unit allows complex scan patterns in the upper hemisphere (AllSky), or within a cone angle of 19° (Profiler VS). Metek complements these systems with in-house developed routines for calculating the vertical wind profiles, for building up to three virtual wind masts and for displaying the output data using the proven Metek Graphics software.
