Empirical techniques

Part of the Air Pollution Problems Series book series (AIRPP)


Input parameters such as diffusion constants and inversion heights are the permanent basic problems of atmospheric modelling. Quite often they are inserted into the computational formulae based on the results of previous experiences made in more or less similar conditions. The next step, that of computing diffusion parameters from real-time monitoring network observations and of using them as input values, was performed by Shieh et al. (1970, 1972). They expressed the diffusion parameters as
with i = x, y, z and where a i (x) is the diffusion parameter at a distance x, u is the wind velocity, t is the diffusion time and α, p are constants.
