Wind and CN2 profiling by single-star scintillation analysis

The spatiotemporal cross-correlation function of single-star scintillation is estimated. From this estimation and using a priori knowledge of the theoretical shape of the correlation peaks, a method for simultaneously measuring horizontal velocity, altitude, and integrated CN2 value for each atmospheric turbulent layer between 2 and 20 km is described. Taylor’s hypothesis is tested for one particular layer and the lifetime of certain turbulent eddies is estimated. Results are in good agreement with two other methods.
