Remote sensing verification of LiDAR and SoDAR devices on Austria’s tallest wind measurement masts

The EWS Testing Centre – the accredited testing facility within the EWS Group – operates what is currently Austria’s tallest wind measurement mast, with a total height of 200 metres above ground level, at the EWS test site in Stetteldorf am Wagram, north-west of Vienna.

The wind measurement mast is the centrepiece of the new EWS Wind Test Site for the purpose of LiDAR and SoDAR verification in accordance with international standards. In this ‘wind laboratory’, remote-sensing-based wind measurement devices are tested to ensure they are functioning correctly before and after wind measurement campaigns. The EWS test site offers 360° unobstructed airflow and optimal wind conditions at the location. Verifications at a height of 200 m reflect the current state of the art in wind measurement technology and reduce uncertainties in wind measurement campaigns and, subsequently, in yield assessments. 

The advantages at a glance:
  • EWS has many years’ experience in verifying a wide variety of RSD devices
  • Conducted by the accredited testing laboratory EWS Testing Centre
  • Verification in accordance with standards (IEC 61400-50-1 & IEC 61400-50-2)
  • Short verification duration thanks to optimal wind conditions and unrestricted sector availability
  • High data availability and precise measurement results
  • High accuracy class of the anemometers (Thies Clima First Class Advanced X)
  • The maximum reduction in measurement uncertainties at the EWS test site leads to high acceptance of our wind & yield assessment reports
  • Reliable and accredited test reports
  • Parallel verification of up to 20 RSD devices
  • Low transport costs due to short transport distances
