Abstract
A new Wind Atlas of Poland has been developed and established as a digital data base. The atlas compiles wind data of Poland and off-shore areas of the Baltic Sea. It includes maps of wind speed, air temperature and solar radiation. In addition, maps show the Weibull parameters of the statistical distribution of the wind speed. Time series of wind speed and wind direction are available every 6 km. Data are provided at 50 m, 75 m, 100 m, 125 m or 150 m above the surface. The wind data are validated with in-situ measurements of wind speed and with operational results from existing wind power plants. To access the huge amount of data a new interface was developed, which allows extremely fast access to the data. This Digital Wind Atlas of Poland is adapted to the needs of the wind industry and is probably the most advanced wind atlas of Poland of today.
