Approaches for estimations of effective turbulent diffusion and energeticparameters from characteristics of anisotropic and isotropic spectra ofperturbations of atmospheric refractivity, density and temperature aredeveloped. The approaches are applied to the data obtained with the GOMOSinstrument for measurements of stellar scintillations on-board the Envisatsatellite to estimate turbulent Thorpe scales, LT, diffusivities,K, and energy dissipation rates, ϵ, in the stratosphere. Atlow latitudes, effective values are LT ~ 1–1.1 m,ϵ ~ (1.8–2.4) × 10−5 W kg−1, andK ~ (1.2–1.6) × 10−2 m2 s−1 at altitudes of30–45 km in September–November 2004, depending on different assumedvalues of parameters of anisotropic and isotropic spectra. Respectivestandard deviations of individual values, including all kinds of variability,are δLT ~ 0.6–0.7 m,δϵ ~ (2.3–3.5) × 10−2 W kg−1,and δK ~ (1.7–2.6) × 10−2 m2 s−1.These values correspond to high-resolution balloon measurements of turbulentcharacteristics in the stratosphere, and to previous satellite stellarscintillation measurements. Distributions of turbulent characteristics ataltitudes of 30–45 km in low latitudes have maxima at longitudes correspondingto regions of increased gravity wave dissipation over locations of strongerconvection. Correlations between parameters of anisotropic and isotropicspectra are evaluated
