This dataset provides the EPA portion of a compilation of different regional gridded inventories, including data from Environment Canada for Canada, the European Monitoring and Evaluation Programme (EMEP) and Netherlands Organisation for Applied Scientific Research (TNO) for Europe, and the Model Inter-comparison Study in Asia (MICS-Asia)’s for China, India and other Asian countries, and gap-filled emission gridmaps of the Emissions Database for Global Atmospheric Research (EDGARv4.3) for the rest of the world (mainly South-America, Africa, Russia and Oceania). The EPA data is included as netCDF formatted datasets at 0.1º × 0.1º resolution for 2010. This was the “raw” data that was incorporated into the global mosaics. Emissions from seven main categories of human activities (power, industry, residential, agriculture, ground transport, aviation and shipping) were estimated and spatially distributed on a common grid of 0.1º × 0.1º longitude-latitude, to yield monthly, global, sector-specific gridmaps for each substance and year. Emission summaries from the supplemental information in the published journal article are also included.
