Level 1 files have been created by Deutscher Wetterdienst, Meteorologisches Observartorium Lindenberg (info@dwd.de) Institute of Geophysics and Meteorology, University of Cologne Julian Steinheuer Julian.Steinheuer@uni-koeln.de 2019-08-15 2020-08-31 600 none 17.3 Falkenberg, Germany This data set contains level 1 and level 2 Doppler wind lidar  measurements during 20190815 and 20200831 from different  configurations and three different instruments (Halo Photonics  Streamline). The purpose of the project part was to evaluate the  ability of lidars to retrieve wind gusts. The instruments were  replaced next to the Falkenberg meteorological tower in order to have  a reference measurement of a sonic anemometer at 90.3m. The level 2  data are reproducible with this  (https://doi.org/10.5281/ZENODO.5780949) code. The data are structured  in folders for years (fesstval_2019 and fesstval_2020), for different  devices (wl_***, sonic), and foldersof the corresponding different  configurations. For each configuration there are the Level 1 files in  level_1_** (where ** denoted the creator) and Level 2 files in  level_2_js. The folder /sonic contains Level 2 files for the sonic  anemometer in 90.3m of the Falkenberg meteorological tower. In the  folders are daily netcdfs-files in SAMD convention with radial Doppler  velocities (level1) and 10 minutes mean wind and wind gust peaks  (level 2). The lidar wl_44 (fesstval_2020) was located in Lindberg  (~5km north of Falkenberg). Quality: The data set does not contain a full time period but the result of a test campaign where configuration changes and breaks where made. The retrieval contains uncertainty estimates for each retrieved wind value. The data are based on a  new approach and further testings are appropriate.
