v. 1. Final report -- v. 2. Fortran program and input/output specification. The urban boundary-layer model, described in a previous report (Pandolfo, et al., 1971), was modified and used in forty test runs. Many of the runs varied the meteorological input about a standard (observed) set. It has, therefore, been demonstrated that an economical, objective, physically consistent, and precisely specified (though with some arbitrary elements) procedure has been achieved for obtaining and predicting the three-dimensional meteorological fields needed. In several of the runs, the input topography, land-water distribution, and other physical characteristics of the underlying surface was varied. The results demonstrate that ready generalization to other regions can be expected. The modeled region was simulated with relatively coarse (8-mile) grid spacing. This is in contrast to other models which deal with pollutants only, and which are based on two-mile grid spacing (Sklarew, et al., 1971; Roth et al., 1971). Nonetheless, the temporal and spatial variations of air temperature, humidity, and wind, are simulated with an encouraging degree of realism. Temporal and spatial variations of CO are also simulated fairly realistically, with somewhat less accuracy than in the model described by Roth, et al. (1971), and with accuracy equivalent to that shown by Sklarew, et al. (1971). It is reasonable to expect improved simulation accuracy with the finer horizontal resolution used in these other models, and the performance of such simulations with this model is strongly urged.
