Air Quality Information for Oxfordshire

This interactive tool allows you to explore annual mean modelled ambient air quality concentration data for NO₂ (Nitrogen Dioxide), PM₁₀ and PM_2.5. This data come from Defra's national Pollution Climate Mapping modelling.

 

Background concentrations represent pollution levels that are not influenced significantly by any single air pollution source or street, but rather by the integrated contribution from all the existing air pollution sources over a wider area.  
 
Roadside concentrations are calculated at a distance of 4m from the kerbside, so they provide an estimate of the increased air pollution concentrations that are associated with nearby traffic. In these maps they are calculated for all urban major road links (A-roads and motorways) throughout Oxfordshire.

These modelled maps are used to assess the UK’s compliance with the Air Quality Standards Regulations, and to locate hot spots for air pollution.

 

If you use the year selector in the top right-hand corner of the map you can scroll through years to see how air quality has improved across Oxfordshire since 2001.
