A field study of factors influencing the concentrations of a traffic-related pollutant in the vicinity of a complex urban junction
Another DAPPLE output, describing analysis of air pollution from traffic at the field site. High levels of spatial and temporal variability along Marylebone Road and in parallel side streets were observed and explained in terms of the key roles of wind conditions, traffic behaviour (especially at junctions) and building topology. The common practice of monitoring air quality at a single point cannot capture this picture and must frequently and considerably underestimate pollution levels (contact: Nicola.Cheetham@tfl.gov.uk). The success of DAPPLE field work was a key enabling element in establishing follow-on activities in London: e.g. ClearFlo (contact: stephen.belcher@metoffice.gov.uk); ACTUAL (contact: j.f.barlow@reading.ac.uk).
