Background maps are updated by Defra periodically due to updates to underlying data, including emissions factors. Local authorities should use the most up-to-date data and supporting tools made available.
UK background maps are made available for a reference year and projection years for a range of pollutants including oxides of nitrogen (NOx), nitrogen dioxide (NO2) and particulate matter (PM10 and PM2.5).
The current base reference year for the data is 2018 and the projections are available up until 2030 for NOx, NO2, PM10 and PM2.5. Available as 1x1km grid file of concentrations for each local authority (per pollutant). Maps are used for all new air quality assessments.
