We propose to use the results of our Phase I proposal to produce a prototype system capable of advanced measurements under a wide range of conditions. This proposal involves the development of all three primary components of the complete system: instrumentation, winching, and lifting platforms. We will add a fast response, three-dimensional hot-film sensor to our Phase I instrument to make wind vector measurements to scales smaller than 1 cm. A specialized winch system will be designed and constructed to allow for optimal operation with both kite and blimp platforms in a highly portable, self-contained unit. Kites and tethered balloons will be employed as the lifting platforms for the system. Existing single line parafoil kites will be modified to limit the maximum tension they produce in high winds, and commercial advertising balloons will be employed in light wind conditions to allow system operation under a wide range of wind speeds. The entire atmospheric measurement system will be tested at various stages of its development at White Sands Missile Range, or another suitable site, and measurement results will be compared with existing instruments and remote sensors available at that site.
Benefits: Capable of addressing a wide range of military research questions in the fields of optical turbulence and diffusion and dispersion, this system will also be attractive to researchers at the university, commercial, and government levels. The modular nature of the system will allow for easy integration of other sensors from third parties, as well as those under development at QEI, including a microwave refractometer, ozone and carbon monoxide sensors.
