Point layers: For the Atlantic coastal region, seven years of modeled mean wind speed data on an approximately 2-km grid were obtained from NREL’s WIND Toolkit (http://www.nrel.gov/grid/wind-toolkit.html). Each 1.2-km BOEM aliquot grid cell was assigned a mean wind speed that corresponds to the nearest 2-km WIND Toolkit grid cell representing the majority of its area. The Weibull parameters were estimated by computing the parameters of a Weibull distribution that has the same mean speed and wind energy as the WIND Toolkit data. This process created a long-term, monthly, and hourly (by month and for the whole 7-year period) Weibull representation of the wind speed for each aliquot. The resulting dataset is intended to provide broad estimates of wind speed variation for the purposes of identifying possible good wind energy sites. It is not intended to provide estimates of possible energy production for the purpose of making offshore wind project investment or financing decisions in specific locations.Explanation of Attributes: Results in the geodatabase are reported on the existing 1.2 km x 1.2 km aliquot grid defined by BOEM for the Pacific coastal region. Wind speed statistics are reported at the center point of each aliquot grid, but represent the mean values over the entire area of each grid cell. The data set delivered to BOEM is a geodatabase consisting of 14 layers. There is one layer for the long-term statistics, one layer for each month, and one polygon layer of aliquots covered by the data. The long-term shapefile includes mean wind speed and Weibull parameters to capture the long-term wind speed distribution of the entire 7-year time series. Each monthly shapefile contains mean wind speed and Weibull parameters for that month overall and for each hour of the day within that month. All times are in PST (UTC-8).Variables starting with ‘WS’ are wind speeds in meters per second, those starting with ‘WK’ are Weibull k parameters (dimensionless), and those starting with ‘WC’ are Weibull c (scale) parmeters in meters per second. The string ‘xxx’ (where xxx is a month) in a variable name means that the parameter has been computed using only values from month ‘xxx’ (e.g., ‘JUN_WS’ is the average wind speed in June). The string ‘Hxx’ (where xx is a number from 0 to 23) in a variable name means that the parameter has been computed using only values from hour ‘xx’ (e.g., ‘JUN_H16_WS’ is the average wind speed at 1600 (or 4:00 PM) in June). Polygon Layers - Polygons were created by creating a raster grid of the point files using the closest approximate x,y distance for a BOEM aliquot block of 0.0175 degrees, reclassifying the raster into wind classes and generating a polygon file from the reclassified raster.
The geodatabase was created by computing statistical wind speed parameters for seven years of wind data from NREL’s WIND Toolkit and placing them on a GIS grid that corresponds to the existing BOEM aliquot lease grid for the Atlantic coastal region.BOEM Geographers created the polygon files (see process steps) from the wind data point files in order to make data more easily viewable for MarineCadastre.gov users. Both the original points and the polygon files created from them are available in the geodatabase.

Wind speed polygon files are computed from monthly and annual point wind speed files generated by NREL under and interagency agreement between NREL and BOEM(M16PG00038). Using ESRIs ArcMap Spatial Analyst the point files from the WIND toolkit were gridded into a 0.0175 degree raster cell size (nearest to the average aliquot block size). The resultant raster was reclassified to the nearest 0.5 m/s wind speed. The resultant raster was then converted into polygons according to the new windspeed classification. One point and one polygon file exists for each month of the year. There is also an annual average dataset
