Relationships between the three major ambient air pollutants -ozone (03), sulphur dioxide (S02) and nitrogen dioxide (N02) -have been explored experimentally using linear regression analysis. It has been shown that the amount of 03 in ambient air is based on the total amount of S02 + N02 and that the concentration of 03 can be predicted from the concentration of S02 + N02. On the basis of the data collected, a modified N02 -03 photolytic cycle has been proposed taking into account dry precipitation of S02 and N02.
