Abstract

A novel algorithm for generating multi-component, high-resolution emission inventories for air quality models (AQMs) was developed, enhancing the 0.01° spatial allocation scheme for points, lines, and surfaces based on land use, population density, and road networks. It incorporated localized chemical species allocation based on recent Volatile Organic Compounds (VOCs) and Particulate Matter (PM) composition, along with time allocation scheme utilizing monthly and hourly non-uniformity coefficients. The algorithm consists of four modules for grid calculation, refined inventory calculation, coarse grid interpolation, and model-ready inventory production. It achieved highly integrated and one-step workflow from raw parameter settings to direct model-ready emission files for simulations with CMAQ and CAMx. The Beijing-Tianjin-Hebei (BTH) region was used as example to introduce the production process and research characteristics of refined emission inventory. The results demonstrated that this algorithm effectively captures the spatiotemporal distribution and dynamics of atmospheric pollutants, offering significant support for emission and simulation research.

Gridemis V2.0：一种高度集成的算法方案，用于空气质量模型中使用的高分辨率和多组分排放清单分配

为空气质量模型（AQMs）开发了一种新的多组分高分辨率排放清单生成算法，增强了基于土地利用、人口密度和道路网络的点、线和面0.01°空间分配方案。它结合了基于近期挥发性有机化合物（VOCs）和颗粒物（PM）组成的局部化学物质分配，以及利用月和小时非均匀性系数的时间分配方案。该算法包括网格计算、精细化库存计算、粗网格插值和模型就绪库存生成四个模块。它实现了高度集成的一步工作流程，从原始参数设置到直接模型就绪的排放文件，用于CMAQ和CAMx的模拟。以京津冀地区为例，介绍了精细化排放清单的生产过程和研究特点。结果表明，该算法能有效地捕捉大气污染物的时空分布和动态，为排放和模拟研究提供了重要支持。
