Multi scanning lidar measurements for resource assessment: a case study in complex terrain

In this talk, we present results of multi-lidar measurements from the Alaiz Experiment (ALEX17), carried out in a collaboration between DTU Wind Energy, CENER and UIB. Dual-Doppler synchronized measurements (125 m a.g.l.) are performed by four WindScanner systems on top of a ridge and a mountain range that are 6km apart. Results provide a first step towards resource assessment using scanning lidars, at the same time featuring the challenges faced to obtain a high data availability. The most common flow patterns are also highlighted, being gravity waves from notherly winds and atmospheric hydraulic jumps from southerly winds. These atmospheric phenomena are going to be better analyzed in an upcoming journal paper.
