The first step in wind data analysis is to obtain reliable and relevant data sources. Depending on your project scope and objectives, you may need different types of wind data, such as wind speed, wind direction, wind power, wind shear, turbulence, and gusts. You can access these from various sources, such as meteorological stations, remote sensing devices, and wind turbines. Meteorological stations are ground-based stations that measure and record wind and other weather parameters at regular intervals. Online databases, such as the Global Wind Atlas, the World Meteorological Organization, and the National Renewable Energy Laboratory can provide you with historical and real-time data from these stations. Remote sensing devices use radar, lidar, or sonar to measure wind and other atmospheric parameters from a distance. Such devices can provide high-resolution and spatially distributed data for complex terrain and offshore locations. Examples of remote sensing devices are the WindCube, the WindScanner, and the ZephIR. Finally, you can use wind turbine data collected by sensors and controllers installed on turbines to monitor and optimize the performance of your system. Examples of such data are the SCADA, the CMS, and the LIDAR.
