NEMO 1km Emissions Data for CONUS 2017

Neighborhood Emission Mapping Operation (NEMO), is an anthropogenic emission dataset over CONUS based on the United States Environmental Protection Agency (US EPA) National Emission Inventories 2017. The fine-scale spatial allocation was achieved through distributing the emission sources using 108 spatial surrogates, factors representing the portion of a source in each 1 km grid. It is produced at hourly intervals for four representative days (Saturday, Sunday, Monday, and other weekdays) each month. Gaseous and particulate pollutants are speciated into model species for the Carbon Bond 6 chemical mechanism. Sources, including nonpoint sources, onroad and nonroad mobile sources, and nonelevated point sources, are grouped in 9 sectors. The hourly and monthly emissions data are stored in NetCDF format and the annual emissions are in shapefile format.
