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 with files corresponding to different configurations. For each configuration there are the Level 1 files in /DWL_L1 and the Level 2 files in /DWL_l2. 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).
Limitations: 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.
