N2 - As part of the “Wind Atlas for South Africa” project, microscale modelling has been carried out for 10 meteorological stations in Northern, Western and Eastern Cape provinces. <br/>Wind speed and direction data from the ten 60-m masts have been analysed using the Wind Atlas Analysis and Application Program (WAsP 10). The wind-climatological inputs are the observed wind climates derived from the WAsP Climate Analyst. Topographical inputs are elevation maps constructed from SRTM 3 data and roughness length maps constructed from SWBD data and Google Earth satellite imagery. Summaries are given of the data measured at the 10 masts for the reference period October 2010 to September 2011. <br/>The main result of the microscale modelling is observational wind atlas data sets, which can be used for verification of the mesoscale modelling. In addition, the microscale modelling itself has been verified by comparing observed and modelled vertical wind profiles at the 10 sites. WAsP generally works well, but modelling of the wind profiles can be improved by using project-specific wind atlas heights and by changing the heat flux parameters of WAsP.
