Responsible party role Point of contact
Resource title Doppler Lidar
Resource abstract The Doppler Lidar data are the Carrier to Noise Ratio (CNR) in dB which is a proxy for the lidar reflectivity at 1.5 Ám (10*Log10((P_signal-P_noise)/P_noise)) and the vertical component of the wind speed (w) in m/s. Time is UTC time. z is the altitude in km.

Quality and validity
Process history and quality information Many cuts can be seen in the data set which are due to a non sufficient regulation of the heat load of the lidar during the experiment. Good quality data are usually below 700 m. At a height of 700 m and 1000 m, the velocity estimates are slightly biased due to parasitic signals. The data user may ask Leosphere for further questions concerning instrument characteristics and signal processing.
