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 That archive is no longer updated but can be found here.美国环境保护署（US EPA）小时级连续排放监测系统（Continuous Emissions Monitoring System, CEMS）数据集，包含小时尺度的二氧化碳（CO2）、二氧化硫（SO2）、氮氧化物（NOx）排放数据与总负荷数据，数据存档自 https://campd.epa.gov/。 本存档包含由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，采用无摩擦数据包（Frictionless Data Packages）格式组织。如需了解本数据集与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 Catalyst Cooperative推出的其他数据存档项目 为实现CEMS数据的常态化更新，本数据集替代了此前PUDL推出的EPA CEMS存档——该旧存档曾为每个州提取一份年度数据文件。该存档现已停止更新，但仍可通过原链接获取。
