The ability to obtain meteorological measurements in the planetary boundary layer for quantification of clear-air turbulence is investigated using the
Small Multifunction Research and Teaching Sonde (SMARTSonde). With the instrumented unmanned aircraft, a series of flights were conducted in the srping
of 2013 to obtain meteorological variables at Kessler Atmospheric and Ecological Field Station (KAEFS) near Purcell, Oklahoma. Flying in step-wise
wise helical ascent patterns allows for the calculation of the structure function parameter, C_T^2. A series of varying methods of calculation are used
to examine which provides a more robust result. Given that the flights were conducted near remote sensing instruments, data collected are compared to
sodar by a comparison of return power. This results in the possibility for verification of remote sensors by in-situ measurements from an unmanned
aircraft system (UAS).
