Download continuous monitoring data

Measurements taken from air pollution monitors and weather sensors are made available for educational and research use by the Council. For commercial use of the data, please request permission from the originating authority.

There are two methods of selecting the data you wish to download; by site or by pollutant. By site - you may choose up to six of the pollutants or weather parameters measured at your selected site between your chosen dates. You will then be shown a graph of the data you have selected and, if you are happy with your selection, you can then download the data. By pollutant - you may choose up to six sites at which your selected pollutant or weather parameter are measured between your chosen dates. A graph of your selected data will be shown and the data can be downloaded.

Please be patient; requests for long time periods may take a while to fetch. If no data are shown for your selected period, the site(s) may have opened at a later date, closed down or be temporarily out of service. Not all sites monitor all parameters.
