During July of 2003, the U.S. DOD, DOE, and Army Research offices sponsored a field experiment (JU2003) in Oklahoma City to
better understand and model atmospheric releases in urban environments. As part of this study, Arizona State University
deployed a coherent Doppler lidar. The ASU lidar was deployed approximately 4 kilometers south of the central business
district with the purpose of characterizing the inflow region. Typical winds during July in Oklahoma are from the south.
The ASU lidar employed a variety of scanning strategies to obtain radial velocity and aerosol backscatter fields. A sampling
of the data gathered will be presented. A unique aspect of the lidar data at JU2003 was that another lidar (with the same
type of laser and software acquisition systems) was simultaneously deployed by the Army Research Laboratory. During portions
of the experiment, the two lidars scanned similar volumes and planes from two different locations. Therefore, retrieval of
vectors from the radial velocity fields is possible. Early retrievals of vectors from co-scanned volumes will be presented.
General operation of the ASU lidar and data availability will be discussed.
