摘要

The forecast of Ozone peaks has very important applications, such as control by authorities of the level of this pollutant, and it is also a necessary tool in Environmental Impact Assessment. Determinists and statistical models can estimate these levels, but they are very expensive to develop and apply, and it takes a long time to run the model. In this paper the authors suggest the use of an empirical model, proposed by Chang and Rudy, where it is related the ratio non-methane organic gasesitrogen oxides (NMOG/NO_x) with the tropospheric Ozone levels reached. The model has been validated with data from different stations over Catalonia (Spain). Finally, it can be concluded that the model is a reasonably effective tool to predict tropospheric Ozone peaks and the range of concentrations that are going to be reached, although the system tends to slightly overestimate the mean values of Ozone. The model works better in NMOG-rich regime than in low values of NMOG/NO_x ratio, so the fit of the model to real data is higher in non-urban stations than in those placed in populated area where emissions of NO_x are proportionally higher.
