Determination of Stratospheric Wind Profiles by Digital Analysis.

Abstract

A program to measure altitude profiles of the horizontal wind velocity in the stratosphere using smoke trail tracers is described. The system for accessing and digitizing photographs of the sunlight scattering trails was updated with new hardware and software. Film plane coordinates of trail center lines were identified by computer programs, and vector triangulation was applied to determine three-dimensional coordinates of the trail. Highly accurate camera orientations were obtained for input to the triangulation procedure by digitizing images of known stars. Time sequences of positions of points on the trail centerline were then processed to determine the horizontal wind field and its vertical shears.
