Home / Wind Measurement Lidars / WindMast PBL – Atmospheric Lidar System

Introduction of atmospheric Lidar System - Leice Windmast PBL

  • WindMast PBL (Planetary Boundary Layer ) wind profile lidar is an atmospheric Lidar system based on the principle of optical pulse coherent Doppler frequency shift detection, which can meet the high-precision and refined measurement requirements of the three-dimensional atmospheric wind field in the atmospheric boundary layer.
  • Real-time output of data products such as wind profile, turbulence intensity, vertical airflow, boundary layer (cloud bottom) height, SNR (signal-to-noise ratio), backscatter intensity, ground temperature and humidity pressure, etc.
  • The PBL Lidar system is widely used in meteorological and climate research measurement, meteorological forecast model assimilation, atmospheric material flux and pollutant regional transmission and diffusion research, low-altitude wind shear detection and many other fields.
