The Army Research Laboratory ARL, Atmospheric Laser Optics Testbed ALOT is a unique experimental facility with which to measure optical turbulence Cn2 intensity and investigate its effects on infrared imaging and laser optics communications. Within the ALOT, an atmospheric boundary layer scintillometer records Cn2 data over a near horizontal, 2.3 km path. The optical path extends from the top of a tall water tower to the Intelligent Optics Laboratory IOL rooftop at ARL. The mid-point elevation of the optical path is approximately 40 m above ground level. In this paper, we present an overview of selected optical turbulence and meteorology data collected at the ALOT facility and identify several viable research areas that focus on optical turbulence Cn2 measurement, modeling, and analysis.
