Description
Summary: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 Zentek et al. (2018; doi:10.5194/amt-11-5781-2018 ). For this data set winds were computed every 50 m up to 1000 m and the data is averaged over time. The averaging time is one hour (+-30min around each full hour) and missing values are removed. A weighted arithmetic mean was used for the u- and v-component as well as for the fit deviation with the weights "1/fit deviation". The backscatter coefficient was averaged without weights. As backscatter was always measured, hours were included even if no wind could be computed due to atmospheric conditions but hours with no reliable data were excluded (e.g. the lidar was turned off; the ship was rocking to hard; etc.). Further detailed information for this measurement ... : The measurements were performed during the Polarstern cruise PS106.2 funded by the Alfred Wegener Institute under Polarstern grants AWI_PS106/1_2_00. The research was funded by the Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung–BMBF) as part of the project CATS ("The Changing Arctic Transpolar System") under grant 03F0776D. ...
