The Province has expressed an interest in the development of a 5-year database of atmospheric conditions at high spatial and temporal resolution to support regulatory dispersion modelling activities and characterization of airsheds outside the Lower Fraser Valley. The focus of this study is to determine if there is a significant improvement in mesoscale model performance when the model is run in hind-cast mode using analysis fields every six hours, rather than real-time mode using forecast fields every three hours. As a test, a series of high resolution (1 km) simulations over the Thomson-Okanagan area of B.C. were conducted with the Regional Atmospheric Modeling System (RAMS). Simulated fields from both modelling strategies were compared to real observations. Bryan McEwen, in consultation with Dr. Peter Jackson of the University of Northern British Columbia (UNBC) was contracted to conduct the study. Atmospheric simulations were run on an SGI Origin 3400 computer, through the UNBC High Performance Computing
