U.S. Army Research Laboratory Meteorological Measurements for Joint Urban 2003
Abstract
The Joint Urban 2003 (JU2003) project, a multi-agency undertaking to study turbulent transport and diffusion in the urban boundary layer, was conducted in Oklahoma City, OK, in summer 2003. The field campaign involved extensive meteorological and gas tracer measurements to investigate the dispersion of simulated contaminants in and around the city. Instrumentation provided by the U.S. Army Research Laboratory's (ARL) Battlefield Environment Division (BED) included a Doppler lidar, a mobile radiosonde system, a temperature/moisture profiling microwave radiometer, and an array of three dimensional (3D) sonic anemometers mounted on five meteorological towers near and outside the central business district (CBD). In this volume, we describe the temperature, wind, turbulence intensity, and heat and momentum flux measurements obtained by the ARL array of sonic anemometers, all of which were confined to the roughness sub-layer (RSL) of the city. We analyze the temporal and spatial variability of wind and turbulence parameters, focusing on day/night and urban/suburban differences and similarities, and extend the analyses to profiles of turbulence data obtained from sonic anemometers mounted on an 85-m pseudo-tower.
