Abstract : Horizontal winds and shears have been computed from 25 rocket released chemical trails. Tables are presented which give vertical profiles of wind speed, heading, and components and the wind shear components. Eight rockets created releases on the up and down leg of their trajectories. Four of these (November 1970: GENIE, HILDA, IDA, JACKIE) were launched within a ten minute interval and one (HELEN) was associated with near simultaneous releases from three other rockets (GRACE, INGER, JOY). These data are suitable for space and time variation studies. Two pairs of trails (UNA-VANESSA and DORA-EVELYN) are suitable for short time difference study since they were launched within an hour of each other. Horizontal and vertical winds were also computed from chemical puffs on the four pairs of up and down trail releases of the November 1970 series. These point wind data are presented in table form. Graphs of the horizontal trail and wind data, and the vertical point wind data for the November 1970 series are also given. (Author)
