Abstract
Pairs of synchronously scanning Doppler lidars measure the average wind speed of flows crossing the parallel ridges at Perdigão, Portugal, with the ultimate purpose of wind resource estimation. The availability of the data from the lidars when they are running is quite low (50–70%). Furthermore, the instruments did only run less than half the time of the experimental period. These figures have to be improved in order for scanning lidars to be a viable option for wind resource estimation. The variations along the ridges are compared to neutral LES calculations making a good match at the upstream ridge but a significantly worse prediction at the downstream ridge. One reason could be an insufficient representation of the terrain. Another unknown is the influence of the atmospheric stability on the flow which is clearly seen by the scanning lidars.
Highlights
Imagine performing an experimental wind resource estimation campaign in complex terrain using long-range Doppler lidars being able to scan arbitrary trajectories
Deployment of vertically profiling Doppler lidars has some of these advantages but they still cover a limited number of positions in the landscape and they may suffer from biases in complex terrain due to the lack of homogeneity in the scanning cone [1]
We investigate the performance of the lidars and make a preliminary comparison with a large-eddy simulation (LES)
Summary
1. Introduction Imagine performing an experimental wind resource estimation campaign in complex terrain using long-range Doppler lidars being able to scan arbitrary trajectories. The base of the wind vectors on each plot are the scan positions seen from above corresponding to the green curves on figure 1.
