WindCube: Advanced Lidar Technology for Wind Measurement
Wind energy is a driving force in the global transition to renewable power. Accurate and reliable wind measurement is critical for optimizing wind farm operations and improving energy yield. One of the most advanced tools in this field is WindCube, a wind measurement technology that utilizes lidar for wind resource assessment, power curve verification, and operational efficiency.
How WindCube Works
WindCube uses Doppler lidar system that provides precise, real-time wind measurements at multiple altitudes. It employs a pulsed laser beam to detect the motion of airborne particles such as dust or aerosols, enabling it to determine wind speed and direction across a range of heights. Developed by Leosphere, a Vaisala company, WindCube offers a compact and portable solution that delivers industry-leading accuracy for wind energy applications.

The system transmits short pulses of laser light into the atmosphere, where they interact with naturally occurring aerosols. As these particles move with the wind, the laser light is scattered back toward the lidar unit, experiencing a frequency shift due to the Doppler effect. By analyzing this frequency shift, WindCube calculates wind speed and direction at multiple altitudes. The system employs a conical scanning pattern, using four beams plus a vertical reference beam to measure wind vectors. This approach provides highly accurate three-dimensional wind field data, covering a range of up to 300 meters above the ground for standard models, with extended-range versions reaching even higher altitudes.
Applications of WindCube
One of WindCube’s key advantages is its ability to deliver high-resolution data in real time. It can be deployed in various locations, from offshore wind farms to complex terrain, offering a flexible alternative to traditional meteorological masts. WindCube is widely used across the wind energy sector for critical applications. Before constructing a wind farm, developers need to assess the wind resource potential at a site. WindCube provides precise wind profiles, allowing engineers to evaluate wind variability, turbulence intensity, and shear effects. These insights help determine the optimal placement of turbines and maximize energy production.
Additionally, wind farm operators use WindCube for power curve verification to ensure turbines operate at their expected efficiency. By comparing real-time wind measurements with turbine output, engineers can validate performance metrics and detect any anomalies that may impact energy production. Real-time wind data from WindCube also enables wind farm operators to optimize turbine control strategies. Advanced forecasting capabilities help predict wind fluctuations, allowing for proactive adjustments to improve grid integration and reduce wear on turbine components.
Offshore wind farms present unique challenges due to their remote locations and lack of traditional measurement infrastructure. WindCube provides a reliable, cost-effective alternative to fixed measurement towers, enabling developers to collect high-quality wind data in marine environments.
Notable Uses of WindCube
WindCube is also used outside of wind farm applications. One noteworthy deployment of WindCube was during the 2020 Australian bushfire crisis, where researchers used the system to analyze how extreme heat and smoke plumes influenced wind behavior. The data collected provided valuable insights into atmospheric turbulence in fire-prone regions, helping refine predictive models for wildfire spread.
More recently, a study conducted in Denmark utilized WindCube to examine wake effects in offshore wind farms, revealing new ways to mitigate energy losses due to turbine interactions. The ability of WindCube to provide granular data on wind dynamics has been instrumental in refining wind farm layouts and improving overall efficiency.
The Future of WindCube Technology
As wind energy continues to expand globally, the demand for high-precision wind measurement solutions like WindCube will grow. Advances in lidar technology are expected to further enhance the system’s accuracy, range, and adaptability. Future iterations may integrate with artificial intelligence and machine learning algorithms to provide even more predictive capabilities, improving wind farm efficiency and operational reliability. Additionally, open-source packages like the Python package, lidarwind, improve the ability to analyze WindCube data.
