SIEPKER, EBJ  and  HARMS, TM. The National Wind Resource Assessment Project of Namibia. R&D j. (Matieland, Online) [online]. 2017, vol.33, pp.105-116. ISSN 2309-8988.

With eleven tall masts equipped with modern wind data acquisition systems, the National Wind Resource Assessment Project (NWRAP) of Namibia is the most comprehensive dedicated wind measurement project undertaken in the country to date. The objective of NWRAP is the provision of high-quality wind data from which reliable wind climates can be identifiedfor relevant parts of the country. The article provides a brief background to the project and proceeds with a description of the development and location thereof, the equipment employed to produce wind data and the processes and methods used to analyse the data. The statistics pertaining to the observed wind climates as identifiedfrom wind speed data observed at two elevations at each of the masts are presented in the results section. The statistics include Weibull parameters and mean wind power density. It is inter alia shown that the best wind resource exists at the site located close to the Southern coastal town of Lüderitz where a resource of 411 W/m2 at approximately 46 m above ground level was identified.
