This study compares wind measurements from two commercial RS instruments against an instrumented mast, in upland (semi-complex) terrain typical of where many wind farms are now being installed worldwide. They are ground-based and can work over hundreds of meters, sufficient for the tallest turbines in, or planned for, production. This limitation has driven the commercialization of two remote sensing (RS) tools for the wind energy industry: The LIDAR and the SODAR, Doppler effect instruments using light and sound, respectively. As wind turbines continue to grow in size, masts for mounting cup anemometers-the accepted standard for resource assessment-have necessarily become much taller, and much more expensive. Detailed knowledge of the wind resource is necessary in the developmental and operational stages of a wind farm site.
