Scottish air quality database (SAQD)

The air quality in Scotland database and website were commissioned by the Scottish Government to provide a centralised source of air quality information for Scotland. The main objectives of the database and website are:

  • to improve the quality of research and data analysis in order to support and evaluate Scotland’s air quality policies;
  • to provide the public with air quality information on their locality in an easily understood format.

The database and website (developed and maintained by AEA Technology on contract to the Scottish Government) were launched on 2 April 2007 and contain a large amount of valuable data obtained from the network of air quality monitoring sites throughout Scotland. The Scottish Government undertakes considerable monitoring of a wide range of air pollutant species as part of joint national programmes run in conjunction with the Department for Environment, Food and Rural Affairs (Defra), the Welsh Assembly Government (WAG) and the Department of the Environment for Northern Ireland (DoENI). In addition, a large number of local authorities monitor air quality as part of requirements of the Local Air Quality Management (LAQM) review and assessment process.

The SAQD contains information and data on the following:

  • location information on air quality monitoring (including substances monitored for, concentration and trend information, type of monitoring, relevant standards and physical details of the sites);
  • maps and graphs showing pollutant trends;
  • analysis and interpretation of data;
  • local air quality management information;
  • pollutant information (on those substances monitored);
  • pollutant impacts (on a local, regional and global scale);
  • information on the types/methods of monitoring used;
  • information on air quality policy;
  • air quality standards which must be met for certain substances.

The Scottish Government also reports annually on both the SAQD and the state of air pollution in Scotland. These reports contain technical information in relation to the operation of the monitoring network & database and analysis of the data to provide pollutant trend data for individual sites and for Scotland as a whole. Both reports can be found on the Scottish Air Quality website (link above).

SEPA is currently working with the Scottish Government (and its contractor) to investigate the opportunities for combining reporting on air quality and presentation of data within both the SAQD and the Scottish Pollutant Release Inventory (SPRI). This should strengthen the existing data facilities and provide both policy-makers and the general public with integrated sources of data and analysis on air quality in Scotland.
