Abstract
We present a method for simultaneous measurement of the vertical distributi on of the optical turbulence strength C-N(2)(h) and wind velocity V(h) in t he Earth's atmosphere, based on an analysis of spatio-temporal based on an analysis of spatio-temporal correlations of stellar scintillation images ob tained with generalized scidar. A statistical comparison of V(h) obtained w ith 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-N(2)(h), to obtain a turbulence profile free of dome c ontribution. Examples of simultaneous C-N(2)(h) and V(h) monitorings are pr esented.
