This work extends the results of a recent study through analysis of turbulence kinetic energy and turbulence spectra, and their role in accurately simulating wind speed, direction, and tracer concentration. These simulations, run using the Weather Research and Forecasting model with the addition of an immersed boundary method, predict transport and mixing during a controlled tracer release from the Joint Urban 2003 field campaign in Oklahoma City. This paper evaluates the representation of turbulence and its effect on transport and dispersion within multiscale and microscale-only simulations in an urban environment. Outlined and information is provided on the data archiving and present Finally, the numerous datasets produced are Not only have the expectationsĬited above been fully met, but very substantial improvements in theĪccuracy of temperatures and winds compared to that of GR2 are achieved The aforementioned fits are compared to those of the NCEP-Department ofĮnergy (DOE) Global Reanalysis (GR2). Of tropospheric temperatures and winds to rawinsonde observations andįits of 2-m temperatures and 10-m winds to surface station observations. Which is seen to be very near the ingested analyzed precipitation fits Presented: precipitation over the continental United States (CONUS), Retrospective production period (1979-2003) is augmented by theĬonstruction and daily execution of a system for near-real-timeĬontinuation of the NARR, known as the Regional Climate DataĪssimilation System (R-CDAS). Following the practice applied to NCEP's GR, the 25-yr NARR Of numerous other datasets that are additional or improved compared to The use of a recent version of the Noah land surface model, and the use
