PUDL Raw EPA Hourly Continuous Emission Monitoring System (CEMS)

US EPA hourly Continuous Emissions Monitoring System (CEMS) data. Hourly CO2, SO2, NOx emissions and gross load. Archived from https://campd.epa.gov/ This archive contains raw input data for the Public Utility Data Liberation (PUDL) software developed by Catalyst Cooperative. It is organized into Frictionless Data Packages. For additional information about this data and PUDL, see the following resources: The PUDL Repository on GitHub PUDL Documentation Other Catalyst Cooperative data archives In order to enable more regular CEMS updates, this dataset replaces a prior PUDL EPA CEMS archive that pulled one annual file for each state. That archive is no longer updated but can be found here.美国环境保护署（United States Environmental Protection Agency, US EPA）连续排放监测系统（Continuous Emissions Monitoring System, CEMS）小时级数据，涵盖小时级二氧化碳（CO₂）、二氧化硫（SO₂）、氮氧化物（NOₓ）排放数据与总负荷数据。本数据集归档自 https://campd.epa.gov/。 本归档文件包含由催化剂合作组织（Catalyst Cooperative）开发的公共事业数据解放（Public Utility Data Liberation, PUDL）软件所需的原始输入数据，其被整理为无摩擦数据包（Frictionless Data Packages）。如需了解该数据集与PUDL的更多信息，请参阅以下资源： - GitHub平台上的PUDL代码仓库 - PUDL官方文档 - 催化剂合作组织的其他数据归档项目 为实现CEMS数据的更常态化更新，本数据集替代了此前按州提取单年度文件的PUDL版EPA CEMS归档数据集。该旧归档数据集已停止更新，但可通过此处获取。
