This dataset contains the EPA submission to the HTAP_v3 emission mosaic for the years 2002-2017 on the HTAP_v3 grid (0.1 degree by 0.1 degree). These data were based on the same inventories used in EPA's Air Quality Time Series (EQUATES) (https://www.epa.gov/cmaq/equates). Data for the years 2000,2001, and 2018 were not provided directly but were extrapolated by the HTAP_v3 mosaic team outside of EPA. For PM2.5 and PM10, EC and OC, separate files for fugitive dust are also provided since the base inventory was adjusted for meteorology or land use.
