Radiometrically and photogrammetrically calibrated photographic images of tracer material released into the upper atmosphere were microdensitometrically reduced. The digital optical density data were computer analyzed by Fourier-transform and configuration space techniques to determine turbulent diffusion coefficients and heating rates, and other parameters describing upper atmosphere turbulence. Turbulent release altitudes were determined by photogrammetric triangulation and by an inverse triangulation method using previously determined wind profiles. Examination of the long term variation of turbopause height suggests that the altitude of the turbopause is a function of the 10.7 cm solar flux. Author
