A SODAR (SOnic Detection And Ranging) measurement campaign is a cost-effective solution for the acquisition of horizontal and vertical wind speed and direction data through the rotor sweep.

Benefits & Uses of SODAR

  • Validate the upper-level shear profile
  • Characterize the wind resource at multiple locations
  • Reduce uncertainty in energy production estimates
  • Provide comprehensive data for turbine suitability studies
  • Characterize site turbulence in greater detail
  • Identify vertical wind speed and inflow angles
  • Measure directional shear (wind veer) across the rotor sweep
  • Assure the highest quality wind turbine generator layout
  • Investigate wind turbine power curve performance

Fast, Flexible, Reliable, and Economical

  • Fast installation and easy transportation
  • Deployable in remote areas
  • Potential for reduction in number of on-site monitoring towers
  • Deploy in difficult terrain where monitoring towers are not feasible

Customizable Deployments

  • Determine appropriate locations and times for deployment
  • Short-term deployments – as little as three months per site
  • Long-term deployments (6+ months) available for larger sites or in cases where tower installation is not possible

Data Analysis and Quality Control Techniques

  • Closely monitor incoming data to ensure minimal data loss
  • Quickly deploy local trained crews to correct any malfunctions
  • Compare tower and SODAR data to determine instrument performance and to identify icing/rain events
  • Build statistical relationship with on-site monitoring towers to determine wind shear characteristics or other needs
