Abstract
Measurements of the variance and scale of the index of refraction fluctuations in the turbulent atmosphere performed in conjunction with a sound propagation study are described. The theory of turbulence generation in the atmosphere is examined and used to develop a model for the functional dependence of variance and scale with altitude from the data. This model is used to calculate the expected turbulence effects for a nonrefracting atmosphere and the results are compared with data from the sound propagation study. This study demonstrates that turbulence effects are smaller for elevated sources than for sources close to the ground. The calculations necessary for a complete description of the turbulence effects are described.
