These background maps are provided to assist UK Local Authorities with their Review and Assessment of air quality, where local monitoring data is not available. Background concentrations are provided for each 1 * 1 kilometre grid square by Local Authority. Concentrations are available for a 2008 base year and at yearly intervals up to 2020.
This tool can be used to justify the process i.e. help assess air pollutant concentrations.
