Some Observations of Meteorological Effects on Optical Wave Propagation
Abstract
Values for the refractive index structure coefficient, (C sub n) squared, were determined from spaced temperature probe measurements and from measurements of the log-amplitude variations in a laser beam. The values of (C sub n) squared obtained from the optical measurements were smaller than the values obtained from the temperature measurements. Variations in (C sub n) squared derived by the two methods were in good agreement even though the values obtained optically are over a 440-meter path while the temperature-derived values are essentially point measurements. The variations in the measured horizontal winds along the leeward side of the optical path showed a structure closely related to the optically derived (C sub n) squared variations.
