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 C2T-. 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 C2T+.
