Emissions by sector were then mapped to spatial grids by country and sector (several intermediate gridded sectors were combined to form the final release sectors for CMIP6Plus). Grid cells that contain more than one country can have portions of emissions from each country. + +For recent decades, emissions were mapped to the grid level largely using the distribution of emissions from EDGAR within each country and gridding sector (usually using year-specific EDGAR grids from 1970 forward). For some sectors, the emissions distribution varies over time, while for other sectors it was held constant. For most emission species, residential combustion is the dominant source by 1850, so emissions from the RCO sector were distributed using HYDE population distributions by 1900 (with blended spatial distributions between 1900 and 1970). For other sectors the emissions distribution within each country was held fixed before 1970. + +Because of the simplifying assumptions, emissions distributions, particularly in earlier years, should not be taken literally. Overall, however, anthropogenic emissions become small relative to either natural sources or mid-to-late 20th century emissions so we anticipate that these assumptions are not likely to have major impacts on global or regional modeling results. + +In this release, large SO2 point sources, along with any co-emitted species, are explicitly represented - largely through use of a SO2 point source catalog developed by [Fioletov et al 2023](https://doi.org/10.5194/essd-15-75-2023). Remaining emissions for any country/sector are distributed using EDGAR or other proxies as described above (after removing any point sources now explicitly represented)> + +More details on the use of point sources in gridding methodology can be found [here](https://zenodo.org/records/6949566/files/CEDS_Point_Source_Documentation.pdf). + +For more details on the gridding methodology see: +Feng, L., Smith, S.
