Abstract |
A plume-in-grid (PinG) approach has been designed to provide a realistic treatment for the simulation of the dynamic and chemical processes impacting pollutant species in major point source plumes during a subgrid scale phase within an Eulerian grid modeling framework. The PinG science algorithms include a Plume Dynamics Model (PDM) processor and a Lagrangian plume module. Simulations were performed with the PinG treatment applied to a group of point sources exhibiting a wide range of NOx emission rates situated in a regional modeling domain encompassing Nashville, Tennessee. Selected plume model results are presented from a case study day from the Nashville/Middle Tennessee ozone study period during July 1995. |
