The spatial dependence of the turbulent air flow over the rooftop of the Recreation, Intramural, and Athletics Building is examined with the use of high frequency sonic anemometers mounted on a mobile platform. Experimentation took place over the course of two weeks from October 17th thru October 29th, 2009 under relatively uniform meteorological conditions. The data presented suggests a region of recirculation located at the leading edge of the rooftop. This separation layer reattaches to the roof downstream at a distance of 20 meters. In addition, this investigation implies the presence of a spanwise variation in vertical wind over the rooftop that must be investigated further upon the implementation of modified experimental techniques
