Abstract

Sonic anemometers are devices that use ultrasound to provide instantaneous wind velocity and sonic temperature measurements. One of these devices, in conjunction with other meteorological equipment, provides characterization of the local atmosphere at a fixed point. Combining multiple sonic anemometers can provide an estimate of the index of refraction structure function, C²_n(z), along a beam path. This work details this process for characterization of an optical propagation path for use in the evaluation of the performance of turbulence measurement instruments. Experimental results are presented from a one-kilometer horizontal path.
