Abstract
Data are presented from the first year of particulate matter (PM sub(10)) monitoring at a number of urban sites in the UK, which comprise the Automatic Urban Air Quality Monitoring Network. The data are used to assess the sources and chemistry of the suspended particulate matter at the various sites in terms of the contribution of vehicular emissions, correlations between PM sub(10) and gaseous pollutants, correlations between PM sub(10) and nitrogen oxides on both a monthly and daily basis, power station contributions to urban PM sub(10) levels, the coarse particle fraction, secondary airborne PM sub(10), and correlations between PM sub(10) and meteorological parameters. The data show that the maximum PM sub(10) values are quite variable, highlighting the impact of local factors. The extensive concentration data are tabulated.
