This is the final report for the year one effort to improve RUSTIC for Coastal, Ocean and Rolling/Rough Terrain Areas. RUSTIC, developed by ITT, is a quasi-CFD wind field modeling software intended for urban domains limited to 2 km x 2 km. This effort produced RUSTIC-CR in order to incorporate physics that are more appropriate to domains on the order of 60 km x 60 km. For larger domains, it was necessary to incorporate new terms into the governing equations as well as treat the turbulence in different ways. The effort focused on incorporating the appropriate planetary boundary layer (PBL) model for these applications. With regards to these improvements, an upgrade to the model thermodynamics was completed, physics for moist boundary layers was added, and the previous turbulence model was replaced with a second-order-closure (SOC) boundary layer model. In addition, the initial surface boundary conditions in RUSTIC-CR were improved by incorporating land use and land cover, sensible and latent heat fluxes, albedo and boundary layer height. The new product model was tested mainly in three different scenarios: Seattle, Colorado Springs, and Oklahoma City.
