National Emission Inventory (NEI) 2019 modeling platform

The 2019 North American Emissions Modeling Platform is based on the 2017 National Emissions Inventory released in the spring of 2020, including updates to specific sectors to represent emissions from 2019. Sectors that reflect 2019-specific emissions include electric generating units and other point sources; wildland, prescribed, and agricultural fires; onroad and nonroad mobile sources; and commercial marine vessels. The data posted here include emissions for each sector output from SMOKE in a CMAQ format. For the inputs to SMOKE including emissions inventories and ancillary data, see the related publication link which also includes a link to a technical support document.

2019年北美排放建模平台基于2020年春季发布的《2017年全国排放清单》构建，并针对特定行业进行了更新，以准确表征2019年的实际排放水平。用于体现2019年排放特征的行业涵盖：发电机组及其他点源、野外火灾、计划受控焚烧与农业焚烧、道路移动源及非道路移动源，以及商业海运船舶。本平台发布的数据包含各行业经SMOKE模型处理后输出的、采用CMAQ格式存储的排放数据。如需获取SMOKE模型的输入数据（包括排放清单及辅助数据集），请查阅相关出版物链接，该链接同时附带技术支持文档的访问入口。相关出版物：美国环境保护署（U.S. EPA），2022年：《2019年排放建模平台》，链接：https://www.epa.gov/air-emissions-modeling/2019-emissions-modeling-platform
