OAQPS 2022 Modeling Platform

The data are part of the 2022 Modeling Platform used to support regulatory actions and technical analyses conducted by the EPA&#39;s Office of Air Quality Planning and Standards. Specifically, this data includes Weather Research and Forecasting Model (v4.4.2) conducted at a 12-km resolution over the Continental United States (12US). MCIP-processed files and wrfcamx-processed (12US1 domain) are also available as part of this dataset to assist in the use of emissions processing and photochemical modeling. These files may be used in downstream applications to generate emissions, photochemical modeling, or dispersion modeling inputs. Additionally, lateral boundary condition files generated using GEOS-CF at 36-km with results translated from GEOS-Chem species available in GEOS-CF to CMAQ cb6/ae7. Simulations for boundary conditions covering the northern hemisphere are also provided. These simulations were conducted using CMAQ v5.4 and GEOS-Chem v14.0.1. The 2022v1 emissions are provided for a 36km grid over North America (36US3) and two 12km grids (12SU1 and 12US2). See the documentation for pictures of the grids. The types of emissions data provided include point sources, nonpoint sources, mobiles sources, fires, lightning NOx, and biogenic emissions. Input files for computing biogenic emissions inline within CMAQ are also provided. README text files are included at multiple levels within the directory structure to explain files at that level. For more information about the emissions, see the below documentation or the 2022v1 web page: <a href="https://www.epa.gov/air-emissions-modeling/2022v1-emissions-modeling-platform">https://www.epa.gov/air-emissions-modeling/2022v1-emissions-modeling-platform</a>

本数据集属于2022年度建模平台的一部分，旨在支持美国环保署空气质量规划与标准办公室开展的监管行动和技术分析。具体而言，该数据集涵盖了在美国大陆进行的天气研究预报模型（v4.4.2）的模拟，分辨率为12公里。此外，包含经过MCIP处理的文件和 wrfcamx处理的（12US1区域）文件，这些文件作为本数据集的一部分，旨在辅助排放处理和光化学模拟的应用。这些文件可用于下游应用中生成排放、光化学模拟或扩散模拟的输入。同时，还提供了使用GEOS-CF在36公里分辨率下生成的边界条件文件，并将GEOS-Chem中可用的物种结果从GEOS-CF转换为CMAQ cb6/ae7。还提供了涵盖北半球的边界条件模拟，这些模拟使用CMAQ v5.4和GEOS-Chem v14.0.1进行。在北美洲（36US3）以及两个12公里网格（12SU1和12US2）上提供了2022v1排放数据。请参阅文档以获取网格图片。提供的排放数据类型包括点源、非点源、移动源、火灾、闪电NOx和生物源排放。此外，还提供了在CMAQ内计算生物源排放的输入文件。在目录结构的多级位置包含了README文本文件，用于解释该级别的文件。有关排放的更多信息，请参阅以下文档或2022v1网页：[https://www.epa.gov/air-emissions-modeling/2022v1-emissions-modeling-platform](https://www.epa.gov/air-emissions-modeling/2022v1-emissions-modeling-platform)。
