| DETAILED NOTES | |
| Purpose This data set was created for the WASA project and the Department of Energy, South Africa. The wind time series were designed to give information on annual, seasonal and diurnal variations of wind speed and direction for Western Cape and parts of Northern and Eastern Cape. Methodology Reference is made to the information and documentation available from www.wasa.csir.co.za. Limitations The operational envelopes of the wind atlas methodology and the WRF model limit the accuracy of the data set. The timeseries data were designed to be used for:
Available documentation The Numerical Wind Atlas for South Africa is a product of the Wind Atlas for South Africa project and is described further on the WASA download pages. |
