The UK Automatic Urban and Rural Network (AURN) is the Environment Agency's compliance network for the reporting of pollutant concentrations the Air Quality Directive (AQD) 2008/50/EC. This was transposed by respective Air Quality Standard Regulations across the UK and the Devolved Administrations. The network provides measurements of a range of pollutants including Particulate size fractions (PM10 and PM2.5) and the following gases: oxides of nitrogen (NOX) (analysers that measure Nitrogen Monoxide (NO) and nitrogen dioxide (NO2)), ozone (O3), sulphur dioxide (SO2) and carbon monoxide (CO). Further details of the current network are available on http://uk-air.defra.gov.uk/.

The Environment Agency requires the supply and installation of the following air quality monitoring instruments:

• Lot 2 - SO2 analyser which is compliant or equivalent with "BS EN 14212:2012 Ambient Air Quality" which uses the standard method for the measurement of the concentration of sulphur dioxide by ultra-violet fluorescence. 

The decision to formally stop the Gas Analyser Lot 2 - SO2 procurement has been made, due to the forthcoming SO2 network reductions
