2014 EPA National Emissions Inventory allocated to the grid cells of InMAP Source-Receptor Matrix

This dataset is the 2014 EPA National Emissions Inventory (NEI) v1 allocated to the individual grid cells of InMAP Source-Receptor Matrix (ISRM). The source types is classified by EPA Source Classification Codes (SCCs). The dataset includes emissions of both primary and secondary PM2.5. Secondary PM2.5 includes four precursors: NOx, SOx, NH3, and VOC. The detailed description of emission processing is in Tessum et al. (2019).

Each shapefile in the dataset is in the format of input file of InMAP/ISRM, which includes the emission amounts of five pollutants (Primary PM2.5, NOx, SOx, NH3, and VOC), stack information (height, diameter, temperature, and velocity), and SCCs. The unit of emissions is \(\mu g/s\). (If these emissions are used directly with the ISRM, the resulting outputs will be concentrations, in units of \(\mu g/m^3\).)
