Popis:	A complete description of urban diffusion and dispersion generally requires knowledge of emission sources, an appropriate dispersion model, atmospheric stability, mixing height and dispersion parameters, etc. To determine the air pollution related to meteorological parameters, a remote sensing acoustic sounding system has been found to be a useful tool. This paper describes the techniques developed at the National Physical Laboratory, New Delhi to determine Pasquill stability classification, mixing height and diffusion coefficients from monostatic sodar echograms. On the assumption that the Gaussian plume model holds good, concentrations of particulate matter with distances have been compared with actually observed values of particulate matter concentration to show the validity of approach
