Abstract

This paper reports on preliminary numerical and analytical results obtained as a part of a study underway for the development of a Lagrangian point source model. The analysis, for the sake of simplicity and computer time saving has been so far restricted to the two-dimensional case of dispersion from an infinite crosswind line source between two solid boundaries (ground and inversion layer) as illustrated in Fig. 1.
