U.S. Great Lakes Offshore Windspeed 90m Height High Resolution

Published by National Renewable Energy Laboratory | Department of Energy | Metadata Last Checked: September 30, 2025 | Last Modified: 2025-09-29T21:50:25Z
The data here provide an estimate of annual average wind speed at 90 meter height above surface for specific offshore regions of the United States. This dataset is a geographic shapefile generated from the original raster data. The original raster data resolution is a 200-meter cell size. To learn more about this project and methodologies, please see the "Assessment of Offshore Wind Energy Resources for the United States" link below. These data were produced in cooperation with U.S. Department of Energy, and have been validated by NREL. For updated gridded long-term average wind data please see the "Global Wind Atlas" resource below. For more information on NREL's wind resource data development, see the "Wind Integration National Dataset (WIND) Toolkit" and the "WIND Toolkit Long-Term Ensemble Dataset" resources.
