In March 2007, the U.S. Army Research Laboratory completed the last of a three phase urban field study that detailed the sampling of airflow and stability around a single building in southeastern New Mexico. Unlike the earlier two Studies, this Study focused on the 4-dimensional characterization of the following flow features: the cavity flow, reattachment zone, side-eddies, canyon flow, velocity acceleration over the roof, and velocity deficit. The Study's field design was based on a Snyder and Lawson's 1994 wind tunnel study, as well as, a 3-dimensional diagnostic urban model. Measurements were acquired over a 2-week period using 12 towers/tripods located along the north, east, south, and west building sides, the roof and in strategic locations on the building's leeside. To minimize the heating/cooling bias, the equinox time period was selected for acquiring the data.
This paper will give a brief overview of the field study and provide a sample of the preliminary results. At the time of this writing, the in-progress data analysis had confirmed the presence of each feature, despite the atypical 2007 March New Mexico �windy season'. Available statistical and graphical results will be included when the paper is submitted.
