A detailed one dimensional radiation model coupled with a comprehensive regional scale photochemical model(STEM-II) is used to evaluate ground level ultraviolet radiation and changes in photochemical oxidant concentrations under potential global change scenarios. The simulations are conducted for a representative metropolitan region in eastern United States. The simulations involve perturbations to radiative flux based on trends of stratospheric ozone loss. The impact of increased radiative flux on tropospheric ozone is analyzed. In addition, the effects of tropospheric pollution levels on ground level radiative flux are studied. For the urban environment increased tropospheric ultraviolet radiation leads to an increase in photochemical production while ground level radiative fluxes are significantly reduced as a result of increased levels of tropospheric ozone production.
