Abstract

The surface roughnesss legth z0 is an important parameter in air quality modelling. Methods for estimating this parameter for the Estaern Highveld, using availabe data, were investigated. The use of existing geographical maps to determine land cover suffers from certain deficiences. Tethersonde wind speed profiles were found to be inadequate for the purpose of the determination of z0, and it would seem that time-averaged wind speed measurements along a mast are required
