Joint Urban 2003
• Major urban study with following components:– Characterization of urban boundary layer– Measurement of flow within and
downwind of tall building core– Investigation of flows in street canyon
including effects of traffic on turbulence– Measurement of surface energy balance
in urban area– Dispersion of tracer into, out of, and
within buildings (indoor dispersion)– Dispersion of tracer throughout the tall
building core and to four km downwind from release
Joint Urban 2003 – Atmospheric DispersionStudy in Oklahoma City
Present Focus: JU2003 (OK City)Validation (What is the Ground Truth?)
