Development of a second-generation mathematical model for urban air pollution—II. Evaluation of model performance

Abstract

The performance of a new comprehensive model for urban-scale photochemical air pollution is evaluated. The model accurately reproduced the important features of ozone (O₃) and nitrogen dioxide (NO₂) distributions over the South Coast Air Basin of California for a two-day period 26–27 June 1974. Various statistical measures of model performance are reported together with predicted and observed concentration time histories at selected monitoring sites. A new technique for estimating error bounds on emission inventories is also described. The method incorporates the influence of uncertainties in both mass emission rates and chemical reactivity.
