This dataset estimates and spatially distributes anthropogenic emissions of five metals (Cd, Cu, Ni, Pb & Zn) and seven air pollutants (CO, NH3, NOx, PM2.5, PM10, SOx & NMVOCs) in the UK, on a 1km x 1km resolution, from 1750 to 2100. The data from 1970 to 2018 are represented by the UK’s National Atmospheric Emissions Inventory and, as such, the Selected Nomenclature for Air Pollution (SNAP) sector classification system is used throughout the entire time series for consistency (see https://naei.beis.gov.uk/ for details). The work was supported by the UK-SCAPE programme funded by Natural Environmental Research Council National Capability (Award NE/R016429/1)
