Over the past 15 years we have witnessed the development of atmospheric dispersion models which include increasingly complex approximations of photochemistry. Unlike existing Gaussian or analytic schemes, the models simulate atmospheric chemical reactions, some of which act at very rapid rates, and therefore involve time steps much shorter than are generally regarded as necessary for transport and dispersion of inert species. The computational demands rise rapidly with the number of chemical species considered, and it is not unusual to see present-day models for urban and regional scales having computer simulation speeds comparable to the real-world events. Computer restrictions have tended to engender decisions to diminish the spatial resolution of the models in order to increase the number of species and reactions treated.
