Results of Coupling the WRF-Chemistry model w/ the SMOKE Emissions Processing/Modeling System

John McHenry, Baron Advanced Meteorological Systems, Raleigh, NC; and C. J. Coats and J. Vukovich

The Sparse-Matrix Operator Kernel Emissions (SMOKE) Processing and Modeling System was developed to meet the high-performance computing requirements for the EPA's Models-3 system during the 1990's. Since that time, it has gone through extensive upgrades for both retrospective analysis studies and for real-time applications (McHenry et al., 2004). To enable the developing WRF-Chemistry model to utilize the advanced computational kernels and models within SMOKE, a new, redesigned version, SMOKE-RT, was developed. Further, the model-coupling enabled version of the Models-3 IO/API was implemented within WRF-Chem. Together, these two advancements have resulted in a SMOKE-enabled version of WRF-Chem.

In this talk, the authors will briefly review the advancements developed for WRF-Chem and then describe the model-coupling strategy. Runs of the system for a summer 2004 case using WRF-Chem's initial emissions package versus WRF-Chem SMOKE will be discussed, and differences between results for ozone and particulates discussed. Finally, the availability of the new system for WRF-Chem developers and users will be reviewd.
