This report describes the preparation of an estimated map of annual mean background nitrogen dioxide concentrations in the Environment Agency Midlands Region for use in the "First Estimate Workbook”. The networks from which N02 data are available are described. The methods that have been used to calculate a UK-wide map of background N02 concentrations are briefly discussed. The UK Nitrogen Dioxide Survey (Stevenson and Bush, 1995 and 1996) provides the most appropriate source of data for use in maps specifically for the Midlands Region. The UK-wide map was used select a subset of measurement sites in the Midlands Region with known comparability of data produced by different laboratories performing analyses this survey. The relationships between these measured concentrations and the surrogate statistics required for calculation of a map are described. The Midlands map calculated using these relationships is presented in a format appropriate for inclusion in a workbook along with approximate factors that can be used to derive statistics such as estimates of kerbside concentrations and 98th percentiles from this annual mean background map.
