| Abstract |
A new particle-in-cell code has been developed and applied to the simulation of photochemical air pollution in the Los Angeles basin. The method is a Lagrangian one in which a parcel of air is followed and the chemistry takes place within it, in contrast to an earlier method in which the photochemical kinetics is considered in a three-dimensional space of fixed Eulerian cells. Although it can be shown that inherent errors are associated with the Eulerian scheme of computation it has not previously been clear how important these errors would be in actual simulations, when compared to the results of Lagrangian chemistry. In the present study the two methods were compared with actual measurements of photochemical air pollution for a selected day in the Los Angeles basin. The report documents the new Lagrangian code and provides a users guide to its operation. |
