The measurement of this data aims to evaluate the wind shear variability at three selected sites in Malaysia. The sites are Kudat in Sabah, Kijal in Terengganu and Langkawi in Kedah. Both sites in Kudat and Kijal is located in coastal areas with few buildings or trees, while the site in Langkawi is a coastal area with many buildings or trees. The variables were measured using the sensors that mounted on the wind mast with the maximum height from 55 m to 70 m from ground level. The variables measured were wind speed, wind direction, temperature, and pressure, while the wind shear data were directly generated using the power law equation. The averaged wind shear based on measured multiple height wind speed at selected sites is larger than the 1/7 law (0.143). Also, the value of wind shear was higher in order Langkawi > Kudat > Kijal. Ultimately, the wind shear data are essential and can be reused in the wind energy potential study, especially for data extrapolation to desired wind turbine hub height.
这些数据的测量旨在评估马来西亚三个选定地点的风切变变异性。这些地点分别是沙巴的古达、登嘉楼的吉亚尔和吉打州的兰卡威。古达和吉亚尔的两个地点都位于沿海地区，建筑物或树木较少，而兰卡威的地点是一个有许多建筑物或树木的沿海地区。这些变量是使用安装在风塔上的传感器进行测量的，风塔距地面的最大高度为55米至70米。测量的变量包括风速、风向、温度和压力，而风切变数据是使用幂律方程直接生成的。基于选定地点多个高度测量风速得出的平均风切变大于1/7定律（0.143）。此外，风切变值的顺序为兰卡威>古达>吉亚尔。最终，风切变数据至关重要，可在风能潜力研究中重复使用，特别是用于将数据外推到所需的风力涡轮机轮毂高度。
