Wind and backscatter profiles measured by a wind lidar during POLARSTERN cruise PS111 (ANT-XXXIII/2, FROST)
This data set includes vertical profiles of wind speed (FF), wind direction (DD), fit deviation (FD) and the backscatter confident (BB) measured by a ship born wind lidar. The definition of the fit deviation, the main processing of the lidar data and an evaluation of the measurements is described in...
