ResumoThis study aims to validate measurements of a wind Doppler Lidar profiler installed in a wind farm at the Brazilian coastline.An experimental setup was deployed in Pedra do Sal site, located inside a 18MW wind farm at the northeast coast of Brazil.The objective is to use wind data from a 100m meteorological tower as reference and correlate wind profile lidar data to analyze deviations and site--specific effects.The measurement campaign covered a one--year period.Results show a good correlation between lidar and tower, with a correlation of R 2 =0.97.However, there is a non--linear behavior of the bias along the wind speed range.The calculated bias for the four analyzed levels is confirmed with a negative skewness and high kurtosis.In conclusion, the studied lidar profiler presented a good correlation with the reference data, but with significant deviations for wind energy applications.The source of the observed bias behavior is still to be better understood.
