Abstract: Air pollution exposure is responsible for millions of premature deaths each year. This large health burden is a concern of policymakers who design local- and national-level mitigation actions to improve air quality and health. Policies informed by an understanding of the sources that contribute to air pollution are better equipped to address this health burden. By characterizing the relationships between emissions, air pollution, and health impacts, emission reductions, including changes associated with decarbonization, can be linked to health benefits. Estimating the sources of air pollution and assessing the impacts of emission changes presents a challenging research objective; air pollution formation is complex, and precursor emissions undergo many physical and chemical processes in the atmosphere. These research and policy challenges are profound; however, the potential societal benefits from addressing them are undeniable. Several approaches are developed that leverage remote-sensing observations, air quality simulations, adjoint calculations, and state-of-the science health impact assessment methods to characterize the sources of air pollution-related health impacts and to assess how changes in anthropogenic emission patterns could impact public health in the future. A second-order contribution calculation is developed to better characterize the non-linear response of ozone to nitrogen oxides. These approaches are applied to a number of different research questions. The air pollution-related health impacts in Brazil associated with fires in the Amazon from 2016-2019 are estimated. The sources associated with urban-scale air pollution-related health impacts in 14 US cities are identified and the benefits associated with radially applied mitigation measures are assessed. Country-scale domestic and imported air quality health impacts are identified and benefits from reductions in transportation and energy generation emissions are estimated. A new domain for the chemical transport model GEOS-Chem and its adjoint is set-up for South America and the decarbonization air quality co-benefits in the city of Santiago, associated with Chile’s nationally determined contributions as part of the Paris Climate Agreement, are estimated.
