We use adjoint sensitivity analysis to examine the responses of a regulatory ozone attainment metric and adverse ozone health effects to location-specific reductions in anthropogenic NOx emissions. We find spatially heterogeneous responses among both attainment- and exposure-based metrics. Emission reductions in the western U.S. exert the most influence on attainment probability-weighted extreme concentrations (PWCs), while emission reductions in proximity to population centres in the eastern U.S. are most beneficial for reducing short-term ozone-related mortality.
