The study to determine the impacts of future changes in stratospheric ozone and surface temperature on urban air quality was carried out in two parts. The first part assesses the quality of existing ultraviolet data and approaches available for using these data to determine chemical photolysis rates. The second part involves testing the photochemical model for a number of urban data sets under conditions of decreased stratospheric ozone and increased surface temperature. The results of the study indicate an increase in ambient ozone, H2O2, and PAN concentration occur for most cities with decreasing ozone column. An increase in ambient temperature results in most cases with an increase in oxidants. PAN, however, which is temperature sensitive exhibits in many cases a decrease with increasing ambient temperature.
