Estimation of the atmospheric structure constants from airplane data

Meteorological measurements in the upper troposphere and lower stratosphere were carried out in the past by several high-flying airplanes. It is a common practice to use the temperature spectrum of the time series obtained from these measurements to compute an averaged value ( over the flight path) of the temperature structure constant C-T(2). In this paper time - frequency techniques are used to obtain an estimate for the local spectra of the temperature, which is utilized to obtain local estimates for C-T(2).
