Abstract. The Modular Emission Inventory Allocation Tool for Community Multiscale Air Quality Model (MEIAT-CMAQ) v1.0 is a resource that enables the refinement of coarse emission inventories by delivering complete temporal, species, and vertical allocations. This tool generates model-ready emission files for CMAQ, and it effectively addresses the challenges concerning the pinpointing of grid information and the spatial allocation for spatial surrogates with specific shapes. These features significantly enhance the accuracy of the allocation of emissions from transportation sectors. Additionally, MEIAT-CMAQv1.0 features an efficient operational algorithm and a modular design, thus conferring greater flexibility and making it suitable for both gridded and tabulated emissions inventories. By inputting pre-assessment and post-assessment emissions separately into the CMAQ model, we observe that post-allocation inventory has a significant positive effect on both O3 and PM2.5 simulations. The development of MEIAT-CMAQv1.0 provides valuable insights into the automated operation of air quality models and the development of emission inventory allocation tools.

Short summary
This tool improves existing methods by providing temporal and species allocation modules and enabling emission file generation in advance for any time period. The tool is also capable of vertical plane distribution for high altitude emissions and accurately tracks road-related emissions, an area overlooked by other tools. It utilizes 50 % of the CPU capacity for efficient parallel processing during allocation.
