The present dataset is part of the Alaiz Experiment-2017 (ALEX17) conducted close to Pamplona, Spain, from Nov/2017 to Jul/2019. The unique feature of this dataset is the scale (~20km^2) and complexity (>500m elevation change) of the topography covered by the measurements. This dataset consists of measurements of five long-range windscanner lidar systems, performing synchronized scanning trajectories that connects and follow both ridges in a 10km Z-shaped transect 125m a.g.l. where the 2D or 3D wind field can be reconstructed. The lidar scans also measure three 2D/3D virtual met masts in strategic points of the domain.
