Due to structural reasons, lattice tower mast can measure high attitude wind speed data compared with cylindrical observation tower mast. However, even in case of measuring wind data using lattice tower mast, there are some uncertainty of flow distortions by tower shadowing. This paper shows accuracy evaluation of wind speed correction method of lattice tower mast using CFD (Computational Fluid Dynamics) simulations. In addition, this paper shows comparison between one-year measurement LiDAR (Light Detection and Ranging) data that can be compared directly and corrected wind data of lattice tower mast by CFD calculation. As a result of performing the wind speed correction using the inflow wind speed ratio by CFD, the uncertainty of corrected wind speed fell by less than uncorrected data.
