Numerical and experimental study on the SO2 pollution produced by Lerdo thermal power plant, Mexico

This paper presents a study on the pollution produced by a fossil fuel plant located in a complex rural environment in México. The study was carried out both experimentally and numerically; experimental measurements were obtained from a monitoring network around the plant. Numerical simulations were carried out employing EPA VALLEY Gaussian model. We are particular interested in annual average ground level concentration of SO2, that is considered the main pollutant emitted by the plant. Comparison of numerical results with experimental data, suggest significant uncertainties involved in the use of traditional Gaussian models.
