Measurement of the microwave structure constant profile

Measurements of the microstructure of refractivity at 9.4 GHz were made in Colorado and Florida up to altitudes of about 29000 ft. The structure function parameter
C_{n}^{2}
was calculated from these data. Examples of the resulting profiles are presented with corresponding profiles of refractivity and temperature. Values of
C_{n}^{2}
varied from about
10^{-13}
to
10^{-17}
m
^-2/3
. The heights of occurrence of maximum and minimum values are summarized.
