During spring and summer of 2016, two WindScanners installed on balconies attached to tall meteorological masts at the Østerild test station for large wind turbines in Denmark, measured the wind flow over land.
The area around the Østerild test station for large wind turbines in Denmark, includes forested sites, flat land, fjords and hilly terain. The “Balconies Experiment” took place from April to August 2016, consisting of two phases, during which the 2 WindScanners from DTU Wind Energy were elevated at 50m and 200m above the ground level. The purpose was to examine the potential terrain signature on the mean wind flow at different heights. 
Mean wind speed for westerly winds at 50m (left) and 200m (right) above ground level. The stars indicate the locations of the two WindScanners. All points shown have data availability higher than the 65th percentile.
