Abstract

Short-term forecasting of ozone and NO2 levels using traffic data in Bilbao (Spain) G. Ibarra-Berastegi ', I. Madariaga ' , E. Agirre ' & J. Uria I University of the Basque Country, Spain 2 Basurto Hospital. Bilbao, Spain Abstract Bilbao is a city with a population of half a million people located in North- Central Spain. In Bilbao, as many other cities in the world, pollution is mainly due to photochemical smog and carbon monoxide. These pollutants are originated by traffic. In this work, models based on Multiple Linear Regression have been built to forecast up to 8 hours ahead ozone and NO2 levels using current and past values up to 15 hours back of ozone, meteorology and traffic measured in the area. The models were built for four locations in the area of Bilbao. Traffic variables were calculated as the mean values of all the sensors in the central area of Bilbao. First, the models were adjusted with data of year 1993 and then, the obtained coefficients were applied to year 1994 whose data
