Abstract A cooperative research and development effort has been conducted to design and implement a plume-in-grid (PinG) modeling techniques into the Models-3 Community Multiscale Air Quality (CMAQ) modeling system in order to address the need for an improved modeling approach to treat major point source emissions. Objectives are to provide an improved characterization of the near-source concentration field and a better far-field regional pollutant pattern due to the impact of the plume-in-grid approach. The conceptual design and an overview of the science processes contained in the PDM in PinG algorithms are briefly presented. Test simulations with and without the PinG treatment for a major No(x) point source are described, and an O(3) concentration pattern from the grid model reveals the impact of the plume-in-grid approach. Subgrid scale plume cell O(3) concentrations are also shown.
