The ability to model air quality dispersion at increasingly smaller resolutions requires a concomitant improvement in the resolution of the gridded mobile source emissions used as input to these models. Two methods are currently used to allocate mobile emissions to grids; because of the limitations associated with these methods, their application is usually restricted to coarser grid resolutions. This paper uses a new mobile emissions inventory model (UCDrive) to explore the spatial distribution of mobile source emissions using finer grid cell resolutions. Our results indicate that the new model improves the precision of the spatial allocation of mobile source emissions, which in turn improves our ability to identify and implement pollutant control strategies.
以越来越小的分辨率对空气质量扩散进行建模的能力，需要同时提高作为这些模型输入的网格化移动源排放的分辨率。目前有两种方法用于将移动排放分配到网格；由于这些方法存在局限性，它们的应用通常仅限于较粗的网格分辨率。本文使用一种新的移动排放清单模型（UCDrive），以更精细的网格单元分辨率来探索移动源排放的空间分布。我们的结果表明，新模型提高了移动源排放空间分配的精度，进而提高了我们识别和实施污染物控制策略的能力。
