Reliable,long-term,public meteorological data has been proven to be a high-priority need of the wind industry.To that end,DOE installed two 135 meter-tall met towers with research-grade instrumentation at the nation wind technology center.After some initial preprocessing and data validation,data from a wide array of sensors are directly published onto a publicly available website.These data are being used by wind energy developers are researchers worldwide to improve the design of wind plants and develop the next generation of wind turbines.
