Title

Evolution Of Near-Ground Optical Turbulence Over Concrete Runway Throughout Multiple Days In Summer And Winter

Abstract

Experimental data are presented that demonstrate the evolution of the anisotropy/isotropy of atmospheric statistics throughout the course of four days (two winter, two summer) near the ground over a concrete runway in Florida. In late January and early February of 2017, a 532 nm near-plane-wave beam was propagated 1 and 2 km at a height of 2 m above the runway, and irradiance fluctuations were captured on a CCD array. In August of 2017, a 532 nm Gaussian beam was propagated 100 m at a height of near 2 m, and fluctuation data were captured on a CCD array. Winter data were processed to calculate the covariance of intensity and summer data processed to calculate the scintillation index. The resulting contours indicated a consistent pattern of anisotropy early in the day, evolving into isotropy midday, and returning to anisotropy in late afternoon. Accompanying atmospheric and wind data are presented throughout the measurement days. © 2018 Optical Society of America
