Description:
In October 2000, scientists funded by the U. S. Department of Energy's (DOE) Chemical and Biological National Security Program (CBNP) conducted a comprehensive field tracer study in an urban environment. The study, known as URBAN 2000, was conducted in Salt Lake City, Utah. The study was designed to measure flow and dispersion at multiple scales, thereby allowing a nested system of atmospheric dispersion models to be tested and evaluated under identical meteorological conditions. A set of atmospheric tracer experiments was conducted to investigate transport and dispersion around a single downtown building, through the downtown area and into the suburban area to the northwest of downtown. A spatially dense array of meteorological measurements was deployed in support URBAN 2000, both in the downtown area and in the suburban area. In addition, the study area was extended beyond the suburban scale by embedding URBAN 2000 in DOE's concurrent region-wide Vertical Transport and Mixing (VTMX) tracer and meteorological study. Both the URBAN 2000 and VTMX studies were focused on investigations of the nocturnal boundary layer in stable to neutral atmospheric conditions. The URBAN 2000 and VTMX experiments were cooperative multi-agency efforts. Under the URBAN 2000 funding umbrella, NOAA's Air Resources Laboratory (ARL) Field Research Division (FRD) deployed meteorological instrumentation at two different sites to support both studies. Two sonic anemometers were deployed by FRD in downtown Salt Lake City during intensive observation periods (IOP) to characterize atmospheric turbulence in the vicinity of the sulfur hexafluoride (SF6 ) atmospheric tracer release site. A 10-m meteorological tower, a phased array Doppler sodar, and a radar wind profiler were also deployed for a three-week period at a site approximately 5 km southwest of downtown Salt Lake City. Many other sites were instrumented with meteorological equipment by other groups participating in the studies. The analysis of all these data sets is beyond the scope of this report. Only the meteorological data acquired by FRD is described herein.
