Abstract Surface observations over urban and rural areas in the United States show somewhat typical diurnal variations of ozone, and thus provide some opportunities to evaluate the performance of air quality models. The study showed positive bias (overprediction) of surface zone concentration during nighttime hours and negative bias (underprediction) during daytime hours in rural areas while there was no apparent bias for urban areas. This study examined the hypothesis that increased vertical resolution can reduce the biases in the model. The authors presented preliminary results of comparative analyses of diurnal ozone concentrations simulated by 15- and 30-layer versions of RADM.
