Experimental determination of two-dimensional spatiotemporal power spectra of stellar light scintillation Evidence for a multilayer structure of the air turbulence in the upper troposphere

Two-dimensional spatiotemporal power spectra of shadow patterns associated with stellar light scintillation has been determined experimentally by optical filtering of the spatial frequencies. The results show evidence for a multilayer structure of the air turbulence in the upper troposphere. Altitude and wind speed can be deduced for each layer. They are in good agreement with wind profiles from meteorological data.
