Combination of laser cloud ceilometer, sonic anemometer, and cw-Doppler lidar for boundary layer measurements

Abstract

The wind field and turbulence of 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 remote-sensing method. From the available techniques Doppler lidar has proved to be the most promising candidate. Therefore, the DLR Institute has combined its well established laser doppler anemometer (LDA) and its laser-based ceilometer with a sonic anemometer.<>
