Abstract: The purpose of this study is to identify the impacts of changing climate and anthropogenic emission changes on current and future air quality in throughout the South Coast Air Basin (SoCAB) and particularly within disadvantaged communities, especially those located adjacent to major transportation corridors associated with goods movement. This study distinguishes the role of meteorological variability and emission changes in altering basin-wide ozone air quality and underscores the urgent demand for source- and racial/ethnic groups- targeted regulation policies toward reducing exposure disparities of air pollution and improving environmental justice in the SoCAB.
