Cn 2 determination by differential temperature probes on a moving platform
Abstract
Experimentally obtained values of the refractive-index structure coefficient, Cn squared, from two differential temperature probe pairs are given for altitudes up to 900 m above the surface. Temperature-difference measurements obtained from a probe pair in motion relative to the atmosphere may require a velocity correction if the probe time constants are long. Velocity-correction factors are developed for probes carried by a small unmanned aircraft.
