Abstract
A plume-in-grid (PinG) treatment has been an integral component of the Community Multiscale Air Quality (CMAQ) modeling system. The PinG approach was designed to provide a realistic treatment of the dynamic and chemical processes governing pollutant concentrations in the plumes emitted from the selected major point source stacks on the subgrid scale. This paper contains an overview of the key components of the current CMAQ plume-in-grid modeling system. A description of the procedures to perform model simulations with the PinG treatment will also be given. In previous public releases of the CMAQ modeling system, the PinG module was capable of treating photochemical processes. A notable update in the current release version of the CMAQ/PinG is the inclusion of a treatment for aerosol formation processes. Model results of selected photochemical and aerosol species from a test application are also presented to illustrate the impact on the gridded concentration field.
