A research and development effort is underway to deal with subgrid scale plumes by the design and incorporation of a plume-in-grid approach in the EPA Models-3 system. The intent of this paper is to highlight the important aspects and methods being considered in this plume-in-grid effort. The principal algorithms under development include a plume dynamics processor designed to provide plume location and size (i.e., horizontal and vertical dimensions) information and a Lagrangian reactive plume module (LRPM). A description is provided of processes and approaches included in the plume dynamics processor with selected preliminary results, and the notable features of the LRPM, which will be embedded in a nested grid model, are highlighted.
