The criteria for selecting the wind measurement sites were based The positions were carefully chosen to cover all of the WASA domain
on the needs to best possibly serve for verification of the wind terrain types and climatology for the modelling to be representative
modelling and the following features: of the WASA domain. They were not chosen because they were the
• Topography: Mountains, escarpments, hills, the slope of hills and windiest or the best locations for wind farms.
the distance to mountain ranges and valleys
• Roughness: Vegetation, forests, agricultural land and the distance Data capturing
to towns and cities The stations measure wind speed at heights of 10 m, 20 m, 40 m
• Communication: GSM network, a radio modem and a satellite and 60 m; wind direction, temperature and barometric pressure.
• Infrastructure: Access, roads, building material and concrete. Readings are sampled with a frequency of 0,5 Hz. Every 10-minute
• Access to power: The distance to the power grid reading of the measurements of average/minimum/maximum/
• Sensitive areas: Airports, nature reserves, game parks, bird standard deviation for the parameters are calculated and recorded

• Land classification: Industrial or agricultural land. See Figure 6.
