Vulcan: High-Resolution Annual Fossil Fuel CO2 Emissions in USA, 2010-2015, Version 3

The Vulcan version 3.0 annual dataset provides estimates of annual carbon dioxide (CO2) emissions from the combustion of fossil fuels (FF) and CO2 emissions from cement production for the conterminous United States and the State of Alaska. Referred to as FFCO2, the emissions from Vulcan are categorized into 10 source sectors including; residential, commercial, industrial, electricity production, onroad, nonroad, commercial marine vessel, airport, rail, and cement. Data are gridded annually on a 1-km grid for the years 2010 to 2015. These data are annual sums of hourly estimates. Also provided are estimates of the upper 95% confidence interval and the lower 95% confidence interval boundaries for each emission estimate. For each uncertainty level, there are 10 individual sector files and one total file. These data are designed to be used as emission estimates in atmospheric transport modeling, policy, mapping, and other data analyses and applications.

Vulcan版本3.0年度数据集提供了关于美国大陆和阿拉斯加州化石燃料（FF）燃烧产生的年度二氧化碳（CO2）排放量以及水泥生产产生的CO2排放量的估算。被称为FFCO2的Vulcan排放数据被划分为包括住宅、商业、工业、电力生产、公路、非公路、商业海运船只、机场、铁路和水泥在内的10个源部门。数据以1公里网格的网格形式按年进行年度汇总，覆盖了2010年至2015年。这些数据是每小时估算值的年度总和。此外，还提供了每个排放估算的上95%置信区间和下95%置信区间边界。对于每个不确定性水平，均有10个单独的部门文件和一个总计文件。这些数据旨在作为大气传输模型、政策制定、制图以及其他数据分析与应用中的排放估算使用。
