A meteorological data-acquisition system for atmospheric propagation studies

Instrumentation for studying the propagation of near-millimeter waves has been designed and implemented at 1-mile-long test site in Sandusky, OH. Measurements of the atmospheric structure functions and the transverse wind velocity along the propagation path is accomplished with a custom-built meteorological data-acquisition network consisting of six towers linked together with fiber-optic data lines. Each tower is microprocessor controlled and includes a three-axis anemometer, a Lyman-alpha hydrometer, and a differential temperature probe, with other meteorological parameters obtained at various locations along the path. A modified ISO-OSI reference model is used as the controlling protocol.<
