DGC-LAWW-Buyer@defra.gov.uk. Additional information: Requirement Background:
The aim of the UUNN is to provide additional local NO2 measurement data for inclusion within the national UK compliance assessment for NO2. Data from the UUNN supplements the established assessment, comprised of data from the Automatic Urban and Rural Network (AURN) and air quality modelling. The programme of work is led by (Joint Air Quality Unit) JAQU and the Environment Agency (EA).

The UUNN is an air quality monitoring network that provides measurements of NO2 concentrations at urban traffic sites. Measurement data is used to assess compliance against the annual mean limit value for NO2 set out in the Air Quality Standards Regulations (AQSR) 2010 (40ug/m3). The AQSR provide detailed siting criteria for assessment of ambient air quality and the location of sampling points for the measurement of air pollutants in ambient air. The network has become the critical data for zones where this annual mean limit is exceeded, and the data is now embedded as part of the ongoing assessment of UK-air compliance. Data capture and date integrity is therefore critical to delivery.
