Verification of lidar visibility, cloud base height, and vertical velocity measurements by laser remote sensing

The wind field and turbulenceof the Atmospheric Boundary Layer are important parameters for various application fields, like meteorology, atmospheric physics, environmental protection, wind-energy utilization, air-traffic control, and-so-on. Their high variability in spatial and temporal scales necessitates a fast remotesensing method. From the available techniques the Doppler Lidar has proved to be the most promising candidate. Therefore, DLR has combined its well established Laser Doppler Anemometer (LDA) and its laser-based Ceilometer with a Sonic Anemometer.
