The data was previously validated by NREL and wind energy meteorological consultants. A series of shapefiles were used to create this merged coverage. The shapefiles were initially generated from a raster dataset with 200m resolution. Seven "Wind Power Classes" were used to break down wind power density (W/m2), where class 7 represents the highest wind resource potential. Areas designated class 3 or greater are suitable for most utility-scale wind turbine applications, whereas class 2 areas are marginal for utility-scale applications but may be suitable for rural applications. Class 1 areas are generally not suitable, although a few locations (e.g. exposed hilltops) with adequate wind resource for wind turbine applications may exist in some class 1 areas. The degree of certainty with which the wind power class can be specified depends on three factors: the abundance and quality of wind data; the complexity of the terrain; and the geographic variability of the resource. Certainty ratings were based on these three factors and can be found in the source document: "Wind Energy Resource Atlas of the United States" (see: Cross Reference section). Purpose: To identify areas of high wind resource potential for the western US. Supplemental_Information: All of the base data in this coverage was originally compiled and published elsewhere.

The wind resource assessment was based on surface wind data, coastal marine area data and upper-air data, where applicable. In data-sparse areas, three qualitative indicators of wind speed or power were used when applicable: topographic/meteorological indicators (e.g. gorges, mountain summits, sheltered valleys); wind deformed vegetation; and eolian landforms (e.g. playas, sand dunes). The data was evaluated at a regional level to produce 12 regional wind resource assessments, the regional assessments were then incorporated into the national wind resource assessment. The conterminous United States was divided into grid cells 1/4 degree of latitude by 1/3 degree of longitude. Each grid cell was assigned a wind power class ranging from 1 to 6, with 6 being the windiest. The assigned wind power class is representative of the range of wind power densities likely to occur at exposed sites within the grid cell. Hilltops, ridge crests, mountain summits, large clearings, and other locations free of local obstruction to the wind are expected to be well exposed to the wind. In contrast, locations in narrow valleys and canyons, downward of hills or obstructions, or in forested or urban areas are likely to have poor wind exposure.
