Doppler wind lidar [HALO Doppler Lidar ©B. Pospichal] HALO Photonics Doppler wind lidar at JOYCE The doppler wind lidar has been out of operation since January 2025. It is currently unclear whether it can be repaired. Principle The backscattered light from an emitted laserbeam is used to measure wind speed. Analysis of doppler shift gives wind speed along the beam. Combination of several beams allows an estimate of the three components of the wind vector. Amount of received backscattered l…
