| Abstract: | Ozone and regional tracers are directly related at a rural Rhode Island site during summer. Unlike elemental tracers and sulfate, ozone has a significant background which appears to be unrelated to regional-pollution sources. Summer ozone concentrations were apportioned among northeastern and midwestern sources using results from regional-scale receptor modeling of pollution aerosol. The Northeast contributed roughly 40% more than the Midwest, but ‘background’ accounted for up to half of the average ozone concentration. |
