Abstract for CMAS conference presentation.
Description:
Many areas of the United States remain out of compliance with the National Ambient Air Quality Standards. Additionally, some states have announced goals or adopted legislation to reduce emissions of carbon dioxide (CO2) and other greenhouse gases (GHGs). Human-Earth system models such as the Global Change Analysis Model (GCAM) can simulate the evolution of the energy system and estimate the associated emissions of both GHGs and traditional air pollutants. A tool has been developed to bridge GCAM and the Community Multiscale Air Quality Model using the Detailed Emission Scaling, Isolation, and Diagnostics (DESID) module, facilitating the simulation of the air quality impacts of alternative future energy scenarios, and better coordination of long-term air, climate and energy planning. In this work we demonstrate the application of this tool to examine the ozone and PM2.5 impacts at 2050 of a suite of GCAM scenarios, such as implementation of a Clean Energy Standard, high levels of electrification in the transportation and building sectors, and a moderate GHG reduction target.
