Abstract
The outer scale of turbulence L0 has been calculated
from values of the refractive-index structure coefficient obtained from spatio-angular correlation
measurements of stellar scintillation. It is found that
L0 ≤ 5 m for a large range of
observations in France, U.S.A., and Chile and that its dependence on altitude
Z follows the same general form at all these sites. The
prediction of profiles is shown to be feasible utilizing
standard meteorological radiosonde data and this
L0(Z) curve. A simple model
based on dimensional analysis and a more complicated stochastic model are
compared, but the latter appears to have no advantage.
