Turning the Tides on Wind Measurements: The Use of Lidar to Verify the Performance of a Meteorological Mast test

This work outlines, through a number of case studies, a cost-effective approach for verifying the performance of a met mast using a continuous wave lidar, ZephIR 300, ensuring that calibration of the data is both accurate and problem-free. Once deployed for mast verification, ZephIR 300 also provides the ability to validate the wind shear model used for a particular deployment, demonstrating a further reduction in the uncertainty associated with the extrapolation of mast data within the wind resource campaign.

Repeatability of ZephIR performance demonstrated across sample of 240 IEC compliant ZephIR 300 performance verifications

This report presents the updated results from over 240 ZephIR 300s validated against a tall IEC compliant meteorological mast. Since 2010, ZephIR have operated the first UK remote sensing test site. With the increasing number of ZephIR 300s being validated against this mast, statistical analysis of validation results robustly shows the repeatability and stability of the calibration of ZephIR 300s.

Validation of measurements from a ZephIR Lidar

A large dataset from a ZephIR 300 has been independently analysed by a team from Loughborough University. The performance has been assessed in comparison to a 91m met mast; wind speed, direction, TI and atmospheric stability have all been examined, and the conclusion is that the lidar is capable of measuring the wind resource to at least the same standard as a met mast.
