This map shows the current pollution levels being measured at the seven automatic monitoring sites across Oxfordshire. Click on a marker to find out more details about each site.
Click on the ‘Diffusion tubes’ in the ‘Control map layers and filters’ box below to see the annual mean concentration of nitrogen dioxide measured at a wider network of non-automatic monitoring sites across Oxfordshire. Due to the high density of locations, sites are clustered to show an average at the default zoom level. Use the zoom function to drill down and see the results for individual locations. Use the year selector to scroll through years to see how air quality has improved across Oxfordshire with time.
This interactive tool allows you to explore annual mean modelled ambient air quality concentration data for NO2 (Nitrogen Dioxide), PM10 and PM2.5. 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.
This map shows the latest air pollution forecast across Oxfordshire. You can view the forecast over the next 5 days by clicking on the drop-down menu at the top of the map. These results are from the UK’s national air quality forecast provided by the Met Office.
