Abstract |
This report discusses the refinement of a grid point model for predicting atmospheric transport and diffusion in an urban boundary layer. In earlier studies, a coarse 8-mile horizontal square grid was used to predict CO concentrations in the Los Angeles Metropolitan area. In this stud, a 2-mile grid for the CO emission has been used to test a recent hypothesis that predictive accuracy can be improved by incorporating a finer horizontal grid resolution to more accurately reflect the spatial distribution of a pollutant emission pattern. However, contrary to expectations, the evaluation statistics show that increasing the degree of horizontal detail in the source emission inventory did not significantly increase the sensitivity and accuracy of the pollutant concentration forecast. When compared to other models, this pollutant forecast is among the most accurate when predicting the overall average concentration and temporal correlation, and approximately as accurate as other primitive equation models in terms of spatial correlation statistics. |
