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

The Vulcan version 3.0 hourly dataset quantifies hourly emissions at a 1-km resolution for the 2010-2015 time period. Estimates are provided of hourly 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. Files for hourly total emissions are also available. Data are represented in space on a 1 km x 1 km grid as hourly totals for 2010-2015. This dataset provides the first bottom-up U.S.-wide FFCO2 emissions data product at 1 km2/hourly for multiple years and is designed to be used as emission estimates in atmospheric transport modeling, policy, mapping, and other data analyses and applications.

Vulcan版本3.0时序数据集，以1公里分辨率量化了2010至2015年期间的小时排放量。该数据集提供了化石燃料（FF）燃烧产生的小时二氧化碳（CO2）排放估计以及水泥生产产生的CO2排放估计，涵盖了美国本土以及阿拉斯加州。Vulcan排放数据被称为FFCO2，并按十个来源部门进行分类，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。此外，还包括了每小时总排放量的文件。数据以1公里×1公里的网格形式在空间上表示，展现了2010至2015年期间的小时总排放量。该数据集为首次提供的美国全境FFCO2排放数据产品，以平方公里每小时为计量单位，覆盖了多年度数据，旨在作为大气传输模型、政策制定、地图绘制以及其他数据分析和应用中的排放估计使用。
