In order to answer these demands there are recent developments and deployments of long-range vertical profiler or fully hemispherical scanning wind lidars.
To validate the measurements provided by such a system, it is possible to make inter-comparisons with a met mast at short distance and with wind profilers radar or sodar at longer distance. But, there are difficulties that may arise from the implementation of this kind of methodology because of the uncertainty related to the campaign set-up and the instruments used as reference.
In that perspective Leosphere and DTU Wind Energy are developing a method to assess the accuracy of the Leosphere's lidars.
In this presentation, we will give a detail description of the method and its results.
