Connecting changes in emissions to air quality is critical for evaluating the effects of a specific policy. Here, we introduce a methodology to aid in assessing the air quality impacts of changes in the energy system. A set of widely varying scenarios that describe alternative potential evolutions of the US energy system is constructed using the TIMES energy system model. For each scenario, an R script is used to communicate future emissions changes to the CMAQ photochemical air quality model. Example results are shown, and the development of the TIMES scenarios is described for users who wish to adapt them to alternate geographies. Possible use cases include evaluating the air quality effects of specific emissions reduction measures or of broad changes to dominant technologies in major sectors such as transportation.

桥接现有的能源和化学品运输模型以加强空气质量政策评估


将排放变化与空气质量联系起来对于评估特定政策的效果至关重要。在这里，我们介绍了一种方法来帮助评估能源系统变化对空气质量的影响。使用 TIMES 能源系统模型构建了一组描述美国能源系统替代潜在演变的广泛变化情景。对于每个场景，使用 R 脚本将未来的排放变化传达给 CMAQ 光化学空气质量模型。显示了示例结果，并为希望使 TIMES 情景适应其他地理位置的用户描述了 TIMES 情景的开发。可能的用例包括评估特定减排措施或对交通等主要部门主导技术的广泛变化对空气质量的影响。
