This is data set includes Doppler wind lidar measurements performed between 14/06/2023 and 03/07/2023 at the rooftop of IPPT PAN (Warsaw, Poland; 52.2067ºN, 20.9811ºE, 134 m a.s.l.) in the framework of PURER-EXP campaign (Polish NCN, PURER-SENS project 2021/40/C/ST10/00023). The system Abrego is a Doppler lidar Stream Line (Halo Photonics), belonging to PI Lucas Alados-Arboledas from the University of Granada (Spain), which is part of ACTRIS-Cloudnet (Illingworth et al., 2007). The system laser emits at 1.5 μm and the detector is heterodyne using fiber-optic technology. The measurements for this data set consisted of continuous vertical measurements with a resolution of 30 m and 1 s in space and time, interrupted by step-stare conical scans with constant elevation of 70° and 12 equidistant azimuth points performed every 30 min, followed by continuous-mode conical sector scans with an elevation of 70° and azimuth angle resolution of 0.88°, and continuous-mode RHI scan with an azimuth of 12.8° and elevation angle resolution of 0.89°.
