Observational analysis of the URBAN2000 field program IOP-10, 25-26 October 2000, for model initialization and comparison

摘要

The effects of urban canopy drag and flow complications in urban canyons have been shown in the observations of the URBAN2000 field program. A preliminary analysis of some observations taken at the VTMX/URBAN2000 field program illuminates some of the difficulties in measuring urban flows and turbulence. For accurate modeling and simulation of urban dispersion, accurate vertical profiles of winds and temperature are required, particularly near the dispersion source. Lessons-learned from the URBAN2000 project will be invaluable for future observational studies, and subsequent simulation, of pollutant dispersion in urban areas. A more detailed analysis of the upper air data and turbulence statistics from the sonic anemometers will be presented in the poster accompanying this paper.
