چکیده

This paper evaluates the concentration estimates from a comprehensive model, The Air Pollution Model (TAPM), developed by Australia’s CSIRO (Commonwealth Scientific and Industrial Research Organization) with observations from a field study conducted in 2005 at Wilmington, a coastal urban area located south of Los Angeles. The performance of TAPM in describing the results from the field study was compared with that of a semiempirical dispersion model. We first provide a brief description of the field study and then present results from the two models.
