Digitization and Analysis of Photographic Images of Stratospheric Smoke Trails.
Abstract
A program of determination of horizontal wind profiles in the stratosphere is described. Photographic records of sunlight-scattering smoke trail tracers released from rockets were digitized, with the film plane coordinates of the trail centers recorded for input to a computer program that calculates spatial locations of sequences of trail points by vector triangulation. Star field photographs provided highly accurate camera orientations for calibration of the triangulation program. Reconstructed three-dimensional trail positions as a function of time were processed to provide horizontal winds and vertical shear at approximately 10 meter vertical resolution. (Author)
