Abstract

The great majority of Gaussian models makes use of the dispersion parameters and classification methods proposed by Pasquill (1961) and later slightly modified by Gifford (1961) and Turner (1964). The Pasquill-Gifford-Turner (PGT) dispersion parameters were deduced from tracer experiments using sources near the ground. In spite of this, they frequently are applied for high sources too. However, comparison with results from dispersion experiments using elevated sources show that the PGT dispersion parameters perform quite poorly. Recently, Weil and Brower (1982, 1984) have shown that significant improvement of model performance can be obtained, even with a model of the Gaussian type, using a physically more well-founded parameterization of dispersion.
