Ionospheric wind analysis by meteoric echo techniques

The meteoric method for finding the velocities of winds in the lower E-region is extended. The previously given procedure for finding vector average wind is shown to be unaffected by the presence of turbulent wind components. A new procedure is worked out for finding root-mean-square values of the horizontal and vertical wind components. By looking at the statistics of the reduction procedures, estimates of the accuracies of the method are found; the sources of error are discussed. Relationships between sample size and accuracy are given. Typical results of the methods are presented.
