WIND Toolkit Offshore Summary Dataset

Published by National Renewable Energy Laboratory | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-12-18T17:36:27Z
This dataset contains summary statistics for offshore wind resources for the continental United States derived from the Wind Integration National Datatset (WIND) Toolkit. These data are available in two formats: GDB - Compressed geodatabases containing statistical summaries aligned with lease blocks (aliquots) stored in a GIS format. These data are partitioned into Pacific, Atlantic, and Gulf resource regions. HDF5 - Statistical summaries of all points in the offshore Pacific, Atlantic, and Gulf offshore regions. These data are located on the original WIND Toolkit grid and have not been reassigned or downsampled to lease blocks. These data were developed under contract by NREL for the Bureau of Oceanic Energy Management (BOEM).

The datetime dataset provides the set of hourly time slices (formatted as YYYYMMDDHHMMSS strings) used to construct this statistical summary for each of the 12 months x 24 hours (hence, 1 to 288):

index = (hour-1)*24 + month
Each of the remaining datasets contains a matrix of size 288 x 581,777 elements. Each of the 288 rows corresponds to the data for a given grid location for each of the 288 month/hour combinations in the masked offshore area of the full WIND Toolkit:

latitude and longitude - the location in the EPSG:4326 projection for that grid point
mean - the mean windspeed at 100 meters in m/s
std - the standard deviation of the windspeed at 100 meters in m/s
wk - the Weibull k parameter of the windspeed at 100 meters in m/s
n - the number of data points used to calculate the statistics"
