Abstract
| - We present a method for simultaneous measurement of the vertical distribution of the optical turbulence strength $C_{\rm N}^2(h) $ and wind velocity ${\vec V}(h)$ in the Earth's atmosphere, based on an analysis of spatio-temporal correlations of stellar scintillation images obtained with generalized scidar. A statistical comparison of ${\vec V}(h)$ obtained with this method and instrumented balloons supports the use of this method. The algorithm used allows for the identification of dome seeing, which can be subtracted from $C_{\rm N}^2(h) $, to obtain a turbulence profile free of dome contribution. Examples of simultaneous $C_{\rm N}^2(h)$ and ${\vec V}(h)$ monitorings are presented.
