Microdensitometric reduction and computer analysis were applied in analyzing radiometrically and photogrammetrically calibrated photographic images of chemical and particulate tracers in the stratosphere, mesosphere and thermosphere. Digitized optical density distributions were processed by Fourier and configuration space analyses to determine turbulent atmospheric heating rates, diffusion coefficients, and other parameters descriptive of upper-atmospheric turbulence. Richardson numbers, heating, and turbulent diffusivity were also determined from wind data derived by the smoke trail method. Author
