The Hestia NE corridor version 1.0 Beta FFCO2 emissions data product represents emissions from the combustion of fossil fuels and cement production in 12 counties in the state of Maryland (6 counties), Virginia (5 counties), and District of Columbia from 2010 to 2015. The emissions are generated using a bottom-up/engineering approach and use the results generated by the Vulcan Project (version 3), an effort to quantify space/time-resolved FFCO2 emissions for the entire United States landscape, as the starting point for the more detailed Hestia analysis. A large number of local data sources are combined to best estimate FFCO2 emissions at fine scales such as air quality emissions data, traffic flow data, building information, sociodemographic information, and fuel statistics. The native spatial resolution of the Hestia data product is a combination of points, lines, and polygons dictated primarily by the underlying data sources and the Vulcan FFCO2 emissions outputs. The output made available here places this information into a regularized grid (0.01 degrees latitude x 0.01 degrees longitude) at hourly and annual temporal resolutions. The files below are NetCDF format files that are compressed with tar and gzip (*.tgz). Each contains Hestia for all sectors for one calendar year indicated in the filename. Annual files contain annual means, while hourly files contain hourly emissions for that calendar year.
