Abstract

Simultaneous crosswind and strength of atmospheric turbulence estimations by the classical laser scintillation method and passive optical method from analysis of the light scattered by a natural or man-made topographic objects in natural daylight illumination conditions are presented. The passive sensing method does not require artificial light sources and lies in the formation of incoherent images of surrounding objects in the natural sunlight and analysis of distortion induced by turbulence between the object and the plane of observation The comparison of estimations of integral crosswind and index of refraction structure constant of air is realized at the same measuring optical path by both methods. Optical measurements of integral characteristics were accompanied by independent local acoustic measurements using sonic anemometers.
