摘要
A method of restoring refraction angle fluctuations in the atmosphere by observations of stellar scintillations from space is given. The restoration is carried out for five observations of star settings from the orbital station ''Mir''. The estimations of rms values of restored refraction angle fluctuations are in agreement with direct measurements of refraction angle and calculations from balloon data. Vertical wavenumber spectra of relative refraction angle fluctuations for the large scales 1 km - 50 m have a universal form with a slope close to -2.
