BRAVO, J. L.; NAVA, M. M.  e  GAY, C.. Linear and regressive stochastic models for prediction of daily maximum ozone values at Mexico City atmosphere. Atmósfera [online]. 2001, vol.14, n.3, pp.113-123. ISSN 0187-6236.

We developed a procedure to forecast, with 2 or 3 hours, the daily maximum of surface ozone concentrations. It involves the adjustment of Autoregressive Integrated and Moving Average (ARIMA) models to daily ozone maximum concentrations at 10 monitoring atmospheric stations in Mexico City during one-year period. A one-day forecast is made and it is adjusted with the meteorological and solar radiation information acquired during the first 3 hours before the occurrence of the maximum value. The relative importance for forecasting of the history of the process and of the meteorological conditions is evaluated. Finally an estimate of the daily probability of exceeding a given ozone level is made.
