The scintillation records of Vega obtained by the Salyut-7 space station are used to calculate Vega scintillation indices in the 20-40 km height range of the ray perigees. It is shown that stellar scintillations could be caused by thin stratified inhomogeneities of temperature, with rms variations between 0.1 and 0.2 K in layers with a characteristic thickness of about 60 km. It is suggested that records of stellar scintillation can be used for sensing the structure of atmospheric temperature fields at high altitudes.
