Dual-Doppler wind reconstruction at Alaiz

This is an animation of synchronized dual-Doppler retrievals from the Alaiz Experiment (ALEX17). The panels show the magnitude (colorbar) and wind direction (arrows) of the reconstructed 2D wind vector projected onto the plane of intersecting beams. This is not the horizontal wind, since in the case of Alaiz, over mountainous terrain, the elevation angles to measure such points were too high (>5 deg). The dual-Doppler measurements are a result of a scan trajectory that follows the terrain at a constant height above ground of 125 m.
