Summary of Performance Verification test done by DNV GL in flat terrain test site
Concurrent Spidar and cup anemometer wind measurements were carried out at the DNV GL Janneby
test site to verify Spidar wind data quality against well-known high quality mast based cup and vane anemometry at measurement heights of 57 m 100 m a.g.l.
Within the framework of ECN project "Comparative Measurements SpiDAR® wind LiDAR system"
(project number 6.00492) ECN reviewed data from the SpiDAR wind LiDAR system and compared it
to the data from meteorological masts (MM5) at the ECN Wind Turbine Test Site Wier-ingermeer (EWTW) in the Netherlands.

The use of elastic Lidars to measure wind velocity in the planetary boundary layer is one of the most advanced and investigated applications of elastic Lidars. Roughly speaking, the various methods to measure wind can be divided into two categories:
Coherent detection and Direct detection.
The measurements have been performed at Experimental Alaiz Wind Farm - Cener, near Pamplona, Spain.
Based on the results of this report, the SpiDAR has shown excellent results in complex terrain up to 118m height.
The wind measurements were taken with a meteorological balloon mounted with 6 anemometers in the range of 50 to 300m and the SpiDAR wind LIDAR.
The measurements have been performed at a flat terrain area in a period of 3 days.
The results exhibit excellent comparison for all covered heights with 100% data availability
