Model for Csubn(2) (Optical Turbulence) Profiles Using Radiosonde Data

摘要

The structure constant, Csubn(2), for optical index of refraction fluctuations isthe key to the design of adaptive optical systems that minimize the effects of turbulence on laser beam propagation. This report explains our model which converts standard radiosonde data into Csubn(2) profiles. The results are compared to directly measured in situ values of Csubn(2) obtained by means of balloon borne thermosondes. The AFGL model is also compared to two other such radiosonde models and we describe the results from three test programs.
