GIS has many applications in wind mapping, analysis and modeling. Geographic data and modeling of wind performance can help site wind turbines. Study of wind patterns also is used for assessing wind damage potential.
The GIS staff at the National Renewable Energy Laboratory provides both national wind resource assessment of the United States and high-resolution wind data. GIS data on surface wind data, coastal marine area data, and upper-air data provides for an analysis of wind resource assessment. The methodology used to make a wind-potential ranking map is described in this 2001 report from the National Renewable Energy Laboratory entitled Geographic Information Systems in Support of Wind Energy Activities at NREL.
3TIER produces commercially available GIS wind data. The company’s global GIS wind data provides monthly and annual wind speed measurements. 3TIER also released a 2001 Wind Performance Map for the United States. The GIS analysis showed areas where wind speeds last year were above the long-term mean wind speeds. The analysis compared wind speed measurements from 2011 with wind conditions averaged over the period 1969-2008.
For the year as a whole, the US experienced above average wind speeds, though month-to-month and regional variability were not uniformly above average across the country. The Pacific Northwest and New England saw wind speeds roughly 5% below average for the year, while a broad section of the US from northern Montana to Texas and the mid-Atlantic states enjoyed a strong wind year with wind speeds 5-15% above normal.
WeoGeo just released two wind related GIS data sets. The data covers wind events between 1955 and 2010 for point locations of wind events and wind swaths.
Both datasets detail the location and date of the event, as well as the wind’s speed, if known. Additionally, starting in the 1980’s, wind related injuries, fatalities, and property loss estimates are also included with the data.
The National Weather Service (NWS) provides freely downloadable GIS wind data in shapefile and KML formats. The range of weather related GIS datasets available including Watch Warning Advisories, precipitation estimates and NEXRAD radar imagery. The nowCOAST GIS Web Mapping and WMS offers a wide range of surface wind observations, analyses, and forecasts for U.S. available via map viewer and WMS as well as other meteorological and oceanographic data and forecasts. The Wind ENergy Data and Information (WENDI) Gateway is intended to serve a broad range of wind-energy stakeholders by providing easy access to a large amount of wind energy-related data and information through its two main interfaces: the Wind Energy Metadata Clearinghouse and the Wind Energy Geographic Information System (WindGIS).
At the state level, the Minnesota GIS Wind Data offers GIS data for 30, 80 and 100 meter wind speeds. Also the Oklahoma Wind Map Products is a web page at the Oklahoma Wind Power Assessment describing the efforts to map the wind power resources of Oklahoma. Includes links to tutorials on calculating wind characteristics.
The Wind Energy Resource Atlas of the United States is available as a an online copy with hyperlinked pages to the volume with a list of viewable maps of the United States. The atlas was created by the Pacific Northwest National Laboratory in October of 1986.Article first published March 23, 2002 and last updated on January 20, 2012.
