UK pollution map data available

News published: 19/05/2011

Modelled 1x1km concentration data from Defra’s national models are now available from UK-AIR. These are produced annually on behalf of Defra to help satisfy the UK’s obligations to report air quality under European legislation. New updates will be provided around autumn of each year.

The maps cover the whole of the UK and are commonly requested data that is often used for research purposes. The map data can be accessed and downloaded from the modelled air quality data page which contains specific information about the outputs to help users select and use the most appropriate data for their needs.

Please note that these maps are distinct from the maps provided for LAQM purposes, which contain additional data of benefit to local authorities and are split out by LA. The maps to be used for LAQM are available at the LAQM Background Maps page.
