Daytime r0 evaluated from vertical microthermal measurements
Abstract
The usefulness of parameter r sub 0 for describing the effect of atmospheric turbulence on wavefront distortion sensitive optical systems has been widely discussed. This paper presents in situ daytime r sub 0 measurements (5500 A, Zenith propagation) obtained from balloon-borne microthermal radiosondes. It is found that the parameter r sub 0 is log normal distributed at various levels aloft and that r sub 0 follows a power law in the 100-10,000-m range. Comparing these results with nighttime ground based observations it is concluded that local turbulence prevails in determining image quality.
