Abstract: Currently the UK Meteorological Office provides a 48-hour NO_x forecast using a box model (BOXURB). This study investigates how a more sophisticated dispersion model, NAME, compares with BOXURB and with routine NO_x ||background|| measurements within ten urban areas in the UK over a six month period. The results show encouraging similarities between the two models and the measurements. In both models, the January-March period is modelled with more skill than the April-June period. It has been statistically shown that NAME performs with more accuracy than BOXURB across a range of urban locations.

Keywords: BOXURB; NAME; NO_x; urban air quality.
